"Angel was highly professional and did the job well and efficiently. He is patient, fair and knowledgeable. The new faucet is working perfect. He also figured out why the dishwasher had suddenly stopped working, fixed it right away. I’d recommend him to anyone and will be using his services again if needed."

"Plumbing 1 builders was the perfect team to come and help us with our needs. We got a full hardware replacement for our shower. They were quick and on time when it came to the quote process. They offered us the most competitive price in our area, while also being the most professional with the overall process. They didn’t try to upsell us on anything or spook us about our current set up, which did happen with other plumbers who came to give us a quote. They were quick and professional with the work as well. Everything exceeded my expectations in terms of execution. On top of that, they caught a weird error that was done by the builders and went out of their way to find a solution. We will most definitely reach out to them for any plumbing needs going forward!"

"I had water damage to the ceiling of my garage. Vicente provided evaluation and written estimate in one visit with attention to details and my customer satisfaction. He took the time to verify my plumbing problem by video taping my water leakage of my bathtub drain pipe with his phone through the broken spaces in the ceiling. He returned the next day with Eduardo, assistant, to complete repair with pipe replacement of old bathtub drain pipes. I was impressed with Vicente's respectful, honest, confident, and professional demeanor with attention to customer satisfaction and service. Vicente exceeded my expectations with exemplary work. Bonus: I discovered afterward that Vicente had fixed my slow flowing sink faucet next to bathtub without request or charge. I would request Vicente again for all my plumbing needs in future. Thank you Vicente. You are special!"

Affordable Plumbers FAQs, answered by experts

To unclog a plumbing vent, you first need to locate it. Look at your home's roofline. The plumbing vent will be a vertical pipe sticking straight up from the roof. Since this pipe runs all the way to the main drain underneath your house, you should also be able to find it in the attic.

Toilet augers are hand-held drain snakes. Most of them come with 3 to 6 feet of cleaning cable and a curved, plastic elbow sleeve to protect your toilet bowl. If your clog does not go beyond the toilet’s wax seal, a 3-foot auger would be sufficient. Otherwise, you may need a 6-foot auger to unclog the drain.

No, a larger well pressure tank will not increase or improve water pressure on its own. The pressure control on the well pump is what determines the water pressure in your home. However, a larger tank does offer other benefits. It can hold more water, allowing you to run it for longer before the pump needs to turn on. Because the pump cycles on and off less frequently, there is less stress and wear on the well system. This can lead to a longer lifespan for the pump and tank, and you may experience fewer pump-related issues that could affect your water pressure in the long run.

If you want to increase your water pressure, you can try one of the following solutions:

• Adjust the tank’s pressure settings to a higher PSI (pounds per square inch).

• Replace your current pump with one that has a higher flow rate (GPM).

• Install a water pressure booster pump in your plumbing system.

• For pressure fluctuations, consider replacing your current setup with a constant pressure system.

Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.

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.
