"Adam , the plumber , is a professional. He explains the issues patiently and logically . My sewer line was clogged up and he used the snake and camera to show me the roots that were causing the problems . He recommended hydro blasting the line in order to remove roots. He responded within minutos of posting on Angie's list. He was puntual and started the job on a Saturday afternoon and completed on a Sunday ."

"I requested a plumber to replace/repair a leaking outdoor faucet. Harry responded to my request and repaired the faucet on a Sunday! Courteous and professional work. As an added project I told him I wanted to replace an existing toilet in a downstairs bath. We went together to Home Depot to purchase a replacement (per his recommendation), which he then installed the same afternoon! Harry will be my first call for any future plumbing work."

Plumbing FAQs, answered by experts

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.

Frost-free faucets should not require outdoor pipe winterization when installed properly. The design of a frost-free spigot ensures that water flows out of the spout instead of sitting inside. Additionally, the shutoff valve for the pipe lives inside your home at the end of a long supply pipe, keeping the waiting water from freezing in outdoor temperatures.

Sometimes when a pipe bursts in a house, it makes a clang or popping noise; however, that doesn’t mean you’ll hear it. Newer pipes tend to be quieter than older pipes. Plus, a pipe can easily burst out of earshot, especially if it’s a floor or two away from you. 

If you do hear an unusual popping noise, consider hiring a plumber to inspect your pipes. Most of the time, you’re more likely to notice a burst pipe either from a visible leak or because water won’t run out of your tap properly.

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.

Yes. There are a variety of standard pipe sizes used in plumbing. The main supply line connecting your home to the street is either 3/4 or 1 inch in diameter. Supply lines are 3/4 inch in diameter. Individual components are 1/2 inch in diameter. Meanwhile, your main drainpipe is often 4 inches wide. Most shower and bathtub drains are 2 inches in diameter, most toilet drains are 3 inches in diameter, and most sink drainpipes are 1 1/4 or 1 ½ inches in diameter.
