| Water heater maintenance generally involves the following:
1. Flushing the Tank: Removing sediment build-up from the tank to improve efficiency and prevent damage.
2. Inspecting the Anode Rod: Checking and replacing the anode rod, which prevents tank corrosion.
3. Checking the Pressure Relief Valve: Ensuring it's functioning properly to prevent excessive pressure build-up.
4. Inspecting for Leaks: Looking for any signs of leakage around the tank or connections.
5. Checking the Temperature Setting: Ensuring it's set to an appropriate level ,typically around 120°F for safety and efficiency.
6. Cleaning the Burner (for gas heaters): Removing any debris that could obstruct proper combustion.
7. Examining the Insulation: Checking that the insulation around the tank and pipes is intact to minimize heat loss.
Regular maintenance can help extend the life of your water heater and ensure it operates efficiently.

| We recommended to flush your water heater once a year.
Regular flushing helps remove sediment and mineral build-up, which can affect the efficiency and lifespan of the heater.
If you have hard water, you might need to flush it more frequently, such as every 6 months.

| A banging noise coming from your water heater is often a sign of sediment buildup. This mineral deposit accumulates at the bottom of the tank and can cause a variety of issues, including:
- Reduced water heater efficiency: Sediment acts as an insulator, preventing the water from heating evenly.
- Premature water heater failure: The buildup can corrode the tank and lead to leaks.
How to Fix It:- Flush the water heater: This involves draining a portion of the water to remove sediment. It's recommended to do this once a year, especially if you have hard water.
- Replace the anode rod: This metal rod helps prevent corrosion but can become depleted over time. Replacing it can help reduce sediment buildup.
If the banging noise persists after flushing or replacing the anode rod, it could indicate a more serious issue with your water heater, such as a cracked tank or a faulty heating element.
In this case, it's best to contact our office and make an appointment.

| Emily,
Rotten Egg Smell from Your Water Heater? Here's Why and What to Do :
A rotten egg smell emanating from your hot water heater is often caused by the presence of hydrogen sulfide gas.
Sulfate-reducing bacteria: These bacteria thrive in warm, stagnant water and can produce hydrogen sulfide as a byproduct.
Corroding anode rod: The anode rod in your water heater is designed to corrode before the tank itself. When it corrodes, especially if it's made of magnesium, it can release hydrogen sulfide
What can you do?
Flush the water heater: This can help remove sediment and bacteria buildup.
Replace the anode rod: If the anode rod is corroded, replacing it can eliminate the odor.
Shock the system: Add chlorine bleach to your water heater to kill bacteria. Consult a professional for the correct amount.
Install a water softener: If your water has high levels of minerals that contribute to bacterial growth, a water softener can help.
Consider a whole-house water filter: This can remove contaminants and improve water quality.
When to call a professional: If you're unable to resolve the issue yourself or if the odor persists, it's best to consult a licensed plumber. They can diagnose the root cause and provide effective solutions.

| I tried flushing it and the smell is still there. Is it safe to shock the system myself, or is that something I really shouldn't attempt without a plumber?

| Good that you're asking before attempting it — this one has some real risk if done incorrectly, so let me walk through it honestly.
Can it be done as a DIY task?
Technically yes, but it's one of the trickier maintenance jobs to do safely, for a few reasons:
Bleach and hot water tanks don't mix casually. You need the right concentration of chlorine bleach relative to your tank size, and too much can damage internal components or leave residual chlorine taste/smell in your water for a while after.
The tank needs to be drained, refilled, and re-drained properly. The general process is: drain the tank, refill partially, add a calculated amount of bleach, let it sit (often several hours), then fully flush and drain multiple times to clear the bleach out completely before using the water again. Getting this sequence wrong can leave chlorine in your water supply longer than intended.
Ventilation and safety matter. If you're working with a gas water heater, you need to be careful around the pilot light and burner assembly while draining/refilling.
It doesn't always fix the root cause. If the smell is coming from a magnesium anode rod reacting with sulfate-reducing bacteria (which is very common), shocking the tank kills the bacteria temporarily, but if you don't also replace the anode rod with an aluminum or zinc one, the smell often comes back within a few months.
My honest recommendation: since flushing alone didn't fix it, this is a good point to bring in a plumber rather than doing the bleach shock yourself. They can do the shock treatment correctly, swap the anode rod to a type less prone to this reaction, and confirm there isn't something else going on (like sulfur bacteria actually living in your well water rather than just the tank, which would need a different fix entirely).
If cost is a concern, at minimum I'd suggest replacing the anode rod yourself if you're comfortable with basic tools — that alone often resolves the odor without needing the bleach shock at all, and it's a more contained, lower-risk task.

| That makes sense, thank you. We're actually on well water, so now I'm wondering if that changes things — could the smell really be coming from the well itself rather than the tank? How would a plumber even tell the difference?

| Good thing you mentioned that — well water changes the picture meaningfully, since sulfate-reducing bacteria and naturally occurring hydrogen sulfide are much more common in well systems than in municipal supplies.
How to tell the difference:
- The cold water test is the simplest first step. Run cold water (not from the water heater) at a tap for a minute and smell it. If the rotten egg smell is present in cold water too, it's coming from your well or water supply itself, not just the tank. If cold water smells fine and only hot water smells, it's isolated to the water heater (usually the anode rod reaction).
- Test at multiple fixtures, not just one — sometimes a smell can seem tank-specific but is actually present faintly throughout the house.
- A water test/analysis is the definitive answer. A plumber or a water treatment specialist can test for hydrogen sulfide levels and sulfate-reducing bacteria directly in a water sample from your well, separate from anything happening inside the tank.
Why this matters for the fix:
- If it's isolated to the water heater, the anode rod swap (as discussed) is usually sufficient.
- If it's coming from the well itself, replacing the anode rod might reduce the smell somewhat but won't eliminate it, since the bacteria/sulfur is present in your water supply before it even reaches the tank. In that case, you're looking at well-specific treatment — options include a chlorination/oxidation system, an aeration system, or a specialized whole-house filter designed for hydrogen sulfide removal (like a catalytic carbon filter), depending on the concentration found in testing.
My suggestion: do that quick cold-water sniff test at a few taps before your plumber visit — it'll help them (and you) understand right away whether you're dealing with a simple tank fix or a whole-water-supply issue, which changes both the scope and cost of what's needed.

| Why does my toilet keep running after I flush it?
My toilet continues to run for several minutes after flushing. Sometimes it stops on its own, but other times I have to move the handle slightly before the water shuts off.
What usually causes a toilet to keep running? Could the problem be the flapper, fill valve, or flush handle?
Is this something I can repair myself, or is it better to replace the entire flush valve?

| Why does my toilet keep running after I flush it?
A toilet that continues running after flushing is usually caused by a problem with one of the components inside the tank. The most common causes are a worn or improperly seated flapper valve, a faulty fill valve, or a flush handle and chain that are not working correctly.
Start by removing the tank lid and watching what happens after you flush. Make sure the flapper closes completely and that the chain isn't too tight or tangled.
If water continues to flow into the overflow tube, the fill valve may not be shutting off correctly. Adjusting or replacing the fill valve can often solve the problem.
A small amount of water leaking past the flapper can also cause the toilet to refill periodically. This is often caused by a worn, cracked, or mineral-encrusted flapper.
These parts are generally inexpensive and can often be replaced without replacing the entire toilet. However, if the tank or flush valve is cracked or the shut-off valve does not work properly, professional service may be the better option.
A running toilet may seem like a minor problem, but it can waste a significant amount of water if left unrepaired. It's worth fixing as soon as the problem is noticed.

| Why is the hot water pressure lower than the cold water pressure?
I've noticed that the water pressure from my hot-water faucets is noticeably lower than the pressure from the cold side. This seems to be happening at several fixtures throughout the house.
The water heater is still producing hot water, but the flow isn't as strong as it used to be.
Could a clogged inlet valve, sediment buildup, a partially closed shutoff valve, or a problem inside the water heater cause low hot-water pressure?
What should I check first before calling a plumber?

| Why is the hot water pressure lower than the cold water pressure?
If the cold-water pressure is normal but hot-water flow is weak at several fixtures, the problem may be somewhere in the hot-water system rather than the main water supply.
Start by checking that the water-heater shutoff valve is completely open. A partially closed valve can restrict hot-water flow throughout the house.
Sediment or mineral buildup can also restrict components inside the system, particularly in areas with hard water. The water heater's inlet screen or other plumbing components may become partially blocked over time.
If the problem affects only one faucet, check the faucet aerator and cartridge first. If several fixtures have reduced hot-water flow, the restriction is more likely to be closer to the water heater.
For a tank water heater, it's also worth checking the hot-water outlet connection and any valves near the heater. On a tankless unit, the inlet filter and heat exchanger should be inspected according to the manufacturer's maintenance procedures.
A water heater that is several years old may also have accumulated significant mineral deposits. Regular maintenance, including flushing where appropriate, can help reduce sediment buildup and maintain performance.
If the hot-water pressure suddenly became much lower, rather than declining gradually, don't assume that the heater simply needs flushing. A partially closed valve, clogged component, failing mixing valve, or plumbing restriction could be responsible.
The most useful first test is to compare hot and cold flow at several fixtures. That helps determine whether the restriction is local to one fixture or affects the entire hot-water system.

| Why does my toilet make a hissing sound when it's not being flushed?
My toilet sometimes makes a quiet hissing or running-water sound even though nobody has flushed it. The sound eventually stops, but then starts again later.
Could this be caused by a leaking flapper or a faulty fill valve? Is there an easy way to determine which component is responsible?
Would replacing the flapper usually solve the problem, or should I replace the entire fill valve?

| Why does my toilet make a hissing sound when it's not being flushed?
A hissing sound from a toilet that isn't being flushed usually means that water is moving through the fill valve or leaking slowly from the tank into the bowl.
The easiest first test is to add a few drops of food coloring to the tank and wait about 10–15 minutes without flushing. If the colored water appears in the bowl, the flapper is leaking and should usually be replaced.
If there is no evidence of water leaking through the flapper but the toilet continues making a hissing sound, watch the water level inside the tank. If water is continually entering the tank and flowing into the overflow tube, the fill valve may not be shutting off correctly.
Also check the chain connected to the flapper. If it is too tight or caught underneath the flapper, the valve may not seal completely.
Mineral deposits can also prevent the flapper or fill valve from operating properly, particularly in areas with hard water. In many cases these components are inexpensive and can be replaced without replacing the entire toilet.
I would troubleshoot in this order:
Check whether the water level is too high.
Perform the food-coloring test.
Inspect the flapper and chain.
Check whether water is entering the overflow tube.
Replace the flapper if it doesn't seal properly.
Replace the fill valve if it continues running after the tank reaches the correct level.
If the toilet is older, replacing both the flapper and fill valve at the same time can be reasonable preventive maintenance, especially if both components show signs of mineral buildup or deterioration.
A continuously leaking toilet may seem minor, but it can waste a surprising amount of water, so it's worth fixing rather than waiting for the problem to become worse.

| Why is my water heater making a clicking noise when it turns on?
My water heater recently started making a clicking or ticking sound when it begins heating. The noise lasts for a few minutes and then stops.
The heater still produces hot water normally, and there are no visible leaks. Could the noise be caused by thermal expansion, sediment buildup, or a problem with the heating element?

| Why is my water heater making a clicking noise when it turns on?
A clicking or ticking sound during heating is not necessarily a sign of a serious problem. As the tank, pipes, and fittings heat up, they expand slightly and can make ticking or clicking sounds as they move against surrounding materials.
However, the type and timing of the noise are important.
If the sound occurs mainly when the heater starts or stops heating, thermal expansion of the tank or connected piping is one possible explanation. If the noise is more like popping, crackling, or rumbling, sediment buildup may be more likely. The existing discussion already identifies sediment as a common cause of unusual water-heater noises.
For an electric water heater, a clicking noise accompanied by reduced heating performance could also justify checking the heating elements and thermostats. For a gas heater, the burner and combustion system should be inspected if the noise is associated with ignition or abnormal burner operation.
A few simple observations can help:
Determine whether the noise occurs only while heating.
Check whether hot-water production has changed.
Listen for popping or rumbling rather than simple ticking.
Look for leaks around the tank and connections.
Check whether the noise is coming from the tank or from the pipes.
If the heater is older and the noise has gradually become louder, sediment accumulation becomes more likely. Regular maintenance, including flushing where appropriate, can help reduce mineral buildup and maintain performance.
If the noise is accompanied by leaking, a relief-valve discharge, unusual gas/burner behavior, electrical problems, or a significant loss of hot-water capacity, the heater should be professionally inspected.
A quiet clicking or ticking during heating can be normal thermal expansion, while popping or rumbling is more suggestive of sediment. The exact sound and when it occurs are important clues.
