"Reliable is awesome, they came right out and they replaced my hot water tank in 6 hours. Gerry really knows what he is doing. The best licensed plumber ever in my 30 years living here. He explained to me, If the hot water unit is not installed a certain way that it could fail in only a couple of years. Always go with a pro that’s what Reliable is ."

"It went great. A great experience from start to finish. We submitted an inquiry as we had a leak on a pipe and bathroom. 5 min after submitting the inquiry we were contacted. 24 hours later we had the plumber come fix everything for a great work done and at the right price. If you need help, don’t hesitate to reach out to them. They are great! 5 star service!"

"As soon as I went on Angieâ s list they contacted me. He asked for pictures of our hot water heater and all the documentation on it. By the end of the day he sent me a quote for two different models. The night before he came to install the new heater he asked to see it to be sure he would have everything he needed. Mr. Rizzo is an excellent plumber and a pleasure to work with. He covered all the floors I would definitely recommend him. He was a rare find!"

"Steven put in a bathroom cabinet for me. He did great work at fair price. He was very professional and honest. He's a hard worker and even made extra effort to get a part that was damaged that another plumber didnt replace. He wouldn't not let that go or leave the job till it was finished. He also double checked everything and tested to make sure it was working. I was very impressed & I will be using him again for other home projects. I recommend him and services to all customers.."

"I called them because my roomate was complaining of a backup in the sink and the tub.  Since he was complaining of these at the same time I assumed it was an issue with the pipe going to the cesspool as I've had an issue with it before (and yes, I used the same company both times).  When they showed up, they looked at the issue and determined it wasn't a problem with the pipe and actually helped me discover and fix the problem (the stopper in the tub had fallen into the drain and blocked water flow).  They even gave me some tips for the sink.  This was a great example of a company going the extra mile to help me solve a problem even though it was outside their area of responsibility.  Very happy with them, will use them again if needed.

"I Highly recommend ALTA Renovation Corp. Their performance and track record exceed all expectations. This is the second large scale job, Jose Diaz and Crew were hired by us. I have been in construction (masonry) for more than three decades, so I’m no stranger to Home Improvements and ALTA by far was the BEST Quality of work performed. They handle all aspects of your work needed. No need to hold up the job because a Plumber or Electrician can’t be there for a week. They do it all, QUALITY work and at Reasonable Price. Jose Diaz, Owner of ALTA is compassionate to your needs and is approachable and understanding. Of course, the job scope changes whiles the job is ongoing, but it never an issue with ALTA. Back to my opening sentence, I HIGHLY RECOMMEND, ALTA, Jose Diaz and Crew. PS The Crew has been with ALTA for some time and they are extremely respectful. They all loved my family, grand kids and dog. ALTA is an 11 on a scale of 1 - 10."

Affordable Plumbers FAQs, answered by experts

Yes. There are a variety of standard pipe sizes used in plumbing. The main supply line connecting your home to the street is either 3/4 or 1 inch in diameter. Supply lines are 3/4 inch in diameter. Individual components are 1/2 inch in diameter. Meanwhile, your main drainpipe is often 4 inches wide. Most shower and bathtub drains are 2 inches in diameter, most toilet drains are 3 inches in diameter, and most sink drainpipes are 1 1/4 or 1 ½ inches in diameter.

Most of the time, the answer is yes, but with an enormous asterisk. While an increase in iron deposits isn’t likely to harm you if consumed, that doesn’t mean you should drink any brown water from your faucets. In our book, it’s better to be safe than sorry and opt for bottled until the issue is resolved.

The air admittance valve, or AAV, is a spring-loaded mini-vent that sits right next to your washer. It acts in place of a standard vent stack connection, opening to let air into the drain whenever pressure builds up. It otherwise stays closed to prevent sewer gas from escaping into your home. This gives the washer’s plumbing system the air it needs when water enters or drains.

You should never pour antifreeze down the drain or outside on the ground. Because it's highly toxic, antifreeze can still impact people and animals long after it drains. Antifreeze can contaminate water and sewage systems, and any that gets into storm drains and water supplies can attract animals and harm those that ingest it.

It is generally recommended to schedule a professional plumbing inspection annually for an average home. However, the ideal frequency can vary. Newer homes may only require an inspection every two years, while older homes, or those with a history of plumbing problems, benefit from more frequent annual checkups. Other factors that might necessitate more frequent inspections include having hard water or mature trees on your property with extensive root systems that could damage sewer and water lines. Regular maintenance helps identify potential issues early, preventing costly repairs, and typically includes checking for leaks, inspecting connections, and ensuring pipes and fixtures are in good working condition to extend the life of your plumbing system.
