"I requested a quote on Sunday night and was able to get the plumber to do an evaluation the following afternoon and provide me a quote which I accepted. He replaced and installed the 2 bathroom faucets that same day. He did a great job and I am very pleased with the work."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"I was given a fair quote for an on-demand water heater. The 2 other companies were either, way overpriced or were charging sales tax on their labor. The project was done in a timely manner. Dave was polite and professional. I wish the clean-up of sediment from the old standard water heater had been cleaned up. It was left for me."

Affordable Plumbers FAQs, answered by experts

Baking soda and vinegar is a great solution for cleaning your sink drain; in fact, it’s our preferred method. Here’s how to unclog your drain with baking soda and vinegar: Pour in a half cup of baking soda, then 1 cup of white vinegar, and let the two bubble for 15 minutes. Then rinse out with boiling water. This method is much safer than using a chemical drain cleaner gel.

Yes, many people choose to bury their sump pump discharge pipes. When you leave the pipe visible in your yard, you might trip over it or accidentally damage it with your lawn mower. Plus, from an aesthetic perspective, hiding the discharge line underground looks nicer than leaving it out in the open. Before burying a sump pump pipe, review your local building codes to make sure your installation is compliant.

If your wall is wet, but there isn’t a leak, it’s likely a result of humidity and condensation from running a hot shower or cooking in the kitchen. The best way to remedy this issue is to run the fan in the bathroom when you’re showering or in the kitchen when you’re cooking. You can also use a dehumidifier to help remove moisture from the air.

Yes, you can use too much plumber’s tape. Adding more tape than necessary will make it difficult to make the pipe connection and has no added benefit. Only wrap the tape around a pipe thread three to six times, depending on the size of the pipe and the thickness of the tape.

The key difference between a standard spigot (or regular hose bib) and a frost-free hose bib is its design to prevent freezing and pipe bursting during cold weather. A standard spigot is a basic outdoor faucet. In contrast, a frost-free hose bib has a longer stem that extends into the heated interior of the house, placing the shut-off valve inside where it's protected from freezing temperatures. This design, often combined with a downward-sloping supply pipe, ensures water drains out of the faucet body when turned off, preventing ice formation. This allows you to leave the water supply on year-round without the risk of pipe damage, making it a valuable choice for regions with harsh winters.
