"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."

"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."

"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."

Affordable Plumbers FAQs, answered by experts

It’s a good time to replace your outdoor faucet at the first sign of a leak that doesn't stop when the knob is turned off. Also, you may want to replace your faucet if there is a great deal of lime build-up, the surface behind the faucet is deteriorating, or the faucet itself is pulling away from the wall. The job doesn’t take more than a few hours and can save you money in the long -run.

Since pedestal sinks are narrow and don’t have a cupboard to conceal pipes, many homeowners change their plumbing to make it less visible. It’s a big reason why installing a pedestal sink is more labor-intensive than other types.

You can prevent pipes from bursting by taking several preventive measures. For example:

  • Keep your pipes from freezing when temperatures drop by setting your thermostat to 55 degrees or higher.

  • Open under-sink cabinets to allow warm air to flow around the pipes. 

  • Let faucets drip to keep water moving.

  • Add insulation to crawl spaces or pipes to keep them warm.

If your toilet is still leaking after replacing the toilet flapper, then you may not have installed the toilet flapper correctly. Double-check that you have placed the flapper over the overflow tube correctly, and check the flapper chain is at the right length. If your toilet is still leaking, then you may have another problem on hand. For example, you may need to replace the toilet wax ring or replace the toilet fill valve if your toilet is wobbly and leaking from around the base.

Any drain in your house requires a water trap to prevent sewer gases from entering the home. Dishwashers don’t have an internal water trap, so they must use an external P trap. The most convenient P trap for the dishwasher is already in the plumbing under your sink.
