A combi-boiler—short for combination boiler—is a type of gas (or sometimes oil) boiler that provides central heating and hot water directly from the mains supply. Unlike traditional systems, it doesn’t require a separate hot-water cylinder or cold-water tank.

In most homes, this means you get hot water whenever you open a tap or run a shower, while the boiler simultaneously supports heating through radiators (or underfloor heating). The key idea is “on demand,” rather than storing hot water in advance.

How a combi-boiler works

When there’s a heating call, the boiler heats water for the central heating circuit. When you turn on a hot tap, sensors detect the flow and switch the boiler to deliver hot water to your taps. Because the system relies on mains water, the boiler’s performance depends on your incoming wat ... Read more »

Toilets look similar at a glance, but the “right” choice depends on your household’s needs—water use, accessibility, installation constraints, and daily comfort. With options ranging from dual-flush models to smart toilets and comfort-height styles, comparing specs can save you money and prevent costly swaps.

First, confirm compatibility with your space and plumbing. Measure the rough-in distance (the space from the wall to the center of the drain) and check whether you need a one-piece or two-piece design for easier maintenance and installation. If you’re replacing an older unit, verify that the floor is level enough for a watertight seal, and consider whether you’ll need new supply lines or a new shutoff valve.

Dual-flush toilets: balance savings and convenience

Dual-flush toilets typically offer two button choices—often a smaller flush for liquid waste and a larger f ... Read more »

A backflow preventer is a plumbing device designed to stop backflow—the unwanted reversal of water flow that can pull contaminants into a building’s drinking-water lines. Instead of water moving normally from the supply into your home or facility, pressure changes can force water to flow in the opposite direction, creating a potential health risk.

Backflow can occur when there’s a drop in water pressure on the public side (for example, during a main break or heavy demand). If your plumbing has certain connections or risk sources, contaminants may be drawn backward through the system.

What backflow preventers protect against

Backflow can move a wide range of substances into potable water systems, including chemicals used in irrigation, wastewater from drains connected to irrigation lines, or other contaminants associated with cross-connections. The goal of a preventer ... Read more »

Sump pumps are one of the few home systems that may sit idle for weeks or months—then suddenly need to perform flawlessly. That’s why establishing a service routine matters: it helps prevent clogs, failures, and water damage when you need the pump most.

While exact timelines vary by model and environment, a practical rule of thumb for many households is monthly testing plus seasonal maintenance. Below is a straightforward schedule you can adapt to your basement’s needs.

Monthly: test the pump and check for warning signs

At least once a month, test your sump pump’s switch and operation. For pumps with a float switch, confirm the float moves freely and the pump turns on when water rises. If your unit includes a high-water alarm, verify it’s functioning as well.
