Plumbing FAQs, answered by experts

If there's no water coming out of the spigot, or barely any water, you might have a clogged water line. Areas with hard water are prone to this problem because the high mineral content in hard water causes build-up in pipes and water lines. This constricts the water flow and causes water to slowly trickle out, if at all.

Plumbers can be held liable for their work for anywhere from a year to six years, depending on where you live, but in most states, premises liability lasts for three to four years. You can contact your state’s licensing board to find out how long your plumber is liable. Your local building department or a consumer protection agency in your area can also confirm the timeline for you.

The most common situation in which you should turn off the main water shut-off valve is if there’s a leak in your home, such as in the kitchen or bathroom. Turning off the water supply can prevent further water damage.

You may want to turn off the valve before leaving for an extended period, in case of leaks or pipe bursts while you’re gone. If you’re going to work on plumbing fixtures or appliances, it’s also a good idea to shut off the main valve to ensure no water flow during repairs or installation.

Yes, you can fit a vanity unit to an existing sink, especially if you plan to custom-build the vanity. With a prefabricated vanity, you’ll likely need to make a few adjustments. It depends on the type of sink, the size of the sink, and the existing plumbing. If you plan to retrofit a sink into a prefabricated vanity, make sure you take precise measurements and that your sink is compatible with the vanity you select. Prefabricated units have a precut sink hole, so you’ll need the size to match your sink.

A cistern works by collecting rainwater from your gutters and downspouts and storing it in a holding tank. The holding tank can be installed above or below ground, and the size will depend on your household needs. The stored water can then be used for household tasks, watering your garden, and even for drinking water.
