Plumbing Heating Companies questions, answered by experts

Most jurisdictions legally require a backflow preventer on your drip irrigation system. Even if you live in a place with less strict laws, installing one is a great idea. If you’re planning to use fertilizers or other chemical additives in your garden, a backflow preventer helps ensure those substances stay outside of your home’s water supply. Depending on the complexity of your irrigation system, you may be able to install one for under $100.

Choosing the right plumbing materials involves balancing durability, cost, and suitability. Common materials include copper, PEX, and PVC.

Before the widespread use of PVC, affixing a ground wire to plumbing pipes was generally considered to be an acceptable workaround. Nowadays, not so much. There are plenty of nonmetallic water pipes and fittings out there, so any ground previously provided by the metallic piping would be interrupted in these cases, which is dangerous.

Yes, you can clean a toilet tank with white vinegar. Before you do, shut off the water supply to the toilet. Then, flush it to empty the tank. Next, combine one part vinegar with one part water in a spray bottle and spray the mixture inside the tank. Let it sit for 10 minutes, then rinse away the vinegar by pouring clean water into the tank. Make sure the tank is empty, then dip a scrub brush in vinegar and clean the tank’s inside walls. Turn the water back on and flush again to rinse away the vinegar.

If you live in a place with cold weather, you can winterize your outdoor spigot whenever you finish using your hose for the year. Start by disconnecting and draining your hose, then store it until springtime. Next, close your water shut-off valve and open the bleeder cap, releasing any water inside, and open the outdoor faucet to get rid of any excess water in the fixture. Finally, put an outdoor faucet cover over your spigot until the weather warms up again.
