"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!"

"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

While you shouldn’t increase the flow of your low-flow toilet by adjusting the water level in the toilet bowl set by the manufacturer, you can make the flow as efficient as possible by ensuring the rim jets under the rim are unobstructed. To do this, use a mirror to look under the rim and scrub them with a toothbrush or a small wire to clear any debris stuck in the holes. You can also watch for leaks, make sure the internal components are in good shape, and replace them if necessary.

Whether or not a power-flush toilet is worth it depends on your toilet needs and your budget. If your bathroom sees a lot of use or you’re concerned about the toilet clogging, then a power-flush toilet may be the right choice. You should also check the pressure requirements to make sure your system can handle the necessary requirements. 

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

Replacing a shower drain P-trap costs $150 to $250 for parts and labor. Costs increase to $350 or more if your shower drain assembly is difficult to access or requires more work (like replacing pipes and fittings). If you’re a knowledgeable DIYer, a new P-trap costs $10 to $45.

You can choose a few different options for outdoor kitchen sink drainage. You can install a dry well about 10 feet away from your home or patio or install a French drain closer by. You can also drain into your home’s plumbing system, but it is more costly versus using a dry well.
