"They contacted me right away and had a plumber out in just a few hours (and it wasn’t an emergency repair!). Tawn was very kind and professional and repaired the toilet quickly. Very happy with Day and Night Plumber and I’ve already scheduled an appt. with them for more work!"

"So, the first one to come and inspect and give an estimate was a different company; if we hadn’t had Prince William Plumbing out here after that, this other company might have scammed us out of many thousands of dollars by replacing our main service line. Prince William Plumbing did a much more thorough investigation and discovered that the problem was a connection to the sprinkler system and not the main line. They saved us so much money, while also being incredibly professional. Even the techs that came out to do the work were awesome. Truly great people at this company."

"I found water on the floor of my basement! Horrors! I got 3 estimates and chose T.QEXCAVATION.Plumbing to do the fix. I liked the work ethic of Terence, the owner who was the guy who did the job. He kept me informed of what was happening and how the project was going, turned the water on when he could and off when he needed to so I had water off and on instead of not which meant the world to me. The job is done, I'm happy with the result and would recommend T.QEXCAVATION.PLUMBING to anyone in need of any kind of plumbing job. He is my plumber from now on."

"They did plumbing services. It was basically the toilet tune-up that they were supposed to do. They fixed it on Friday but on Sunday, it did not work again. Took one more week to get out here and they still have to come back to replace the toilet. At the end of it all, that didn't happen."

"1stopmechanical responded quickly to my request for quote of sewer line inspection. Upon inspection, the sewer line from the house to main sewer line had to be replaced. They provided a reasonable quote and completed the installation of the sewer line within 2 days. They were very professional and I would recommend them for any plumbing service."

Plumbing FAQs, answered by experts

Yes, a dripping faucet can increase your water bill. Leaking faucets use up more water than you’d think. According to the Environmental Protection Agency, a faucet that drips once per second can waste more than 3,000 gallons of water per year. If you have more than one dripping faucet, your water bill can increase even further. 

If you’ve accessed the bolts and nuts that hold your toilet seat in place and can’t unscrew them, it’s possible that they were overtightened or that the material corroded over time, making it impossible to unscrew. If that’s the case, you can either call in a plumber for help, or you can DIY a solution if you’re careful. Lay down masking tape around the mounting bracket and then use the tape as a surface to lay a hack saw blade. Move slowly to cut through the bracket and bolt, being careful not to damage the porcelain in the process.

The plumbing industry has standardized the sizes for bathtub drains. They are 1 1/2 inches wide to fit all standard bathtubs from 14 to 26 inches deep. The standard sizing is to ensure that the drain fits into the P trap, a special part of your piping that prevents sewer water from bubbling up into your home (yuck).

You cannot replace a shower valve without turning off the water. Always turn your water off before doing any kind of plumbing work—and this project is no exception. Turning off the water is a best practice for personal safety and to keep things in your home dry.

If you notice smells or clogs, you’ll know something’s wrong with your shower drain P-trap or the plumbing. Most of the time, smells and clogs are due to a clogged P-trap. However, in some instances, you may smell sewage. If this happens, open your windows and contact a plumber to help. They can do a plumbing inspection and let you know if anything needs to be repaired or replaced. Common culprits are a dry drain, cracks in the plumbing, or a clogged vent.
