Practice makes perfect, and Varsity has been at it for over half a century! What began with a Navy veteran’s simple dream — to teach the value of honest, hands-on work to his children — has grown into one of Long Island’s most trusted resource for plumbing, heating and air conditioning services. Varsity’s mission has always been clear: to serve our neighbors with integrity, solve home service challenges with innovative solutions, and provide lasting results. Our dedicated crew is background-checked, rigorously trained in the latest technology, and excited to exceed your expectations. Above all Varsity is here to EARN your trust—not just for today, but for years to come. Let’s tackle your home service needs with the quality and care you deserve!

"Efficient and clear process, nice crew, quick and clean execution. It would score 4.5 as there were a couple of opportunities for improvement identified (including surprising problems with running a communication cable, and a trivial unnoticed misconnection sorted out the next day by a dedicated technical help call), but overall an outstanding service."

We service all of Suffolk as well as Nassau Counties all our work is priced by the job and not by the time always free estimates. fast service senior discounts- vets-disabled people. also payment plans available . just ask.

"I had to hire another cesspool co. My toilet wouldn?t flush and was insisting on me to get a new cesspool. A different company came this afternoon on time. Did say that I could use a new cesspool too. But when I told him my toilet couldn?t flush this co asked why couldn?t the co that came yesterday do it? I said I don?t know. When the new co lifted the lid up , they asked why didn?t the other co yesterday put treatment in my cesspool. They then came inside, unclogged the toilet and treated the cesspool for less money. "

Plumbing questions, answered by experts

The likely culprit is an air lock somewhere in your pipes. This is especially true if the warm water upstairs is accompanied by a decline in water flow. Other causes of this issue include frozen pipes, leaks, damaged supply lines, and more. There’s a simple DIY fix to try for air locks: Turn the hot water and cold water faucets on for a minute, then turn off the cold water and then the hot water. Repeat this process two or three times. 

The most common types of backflow preventer devices depend on the purpose of the installation. For example, Portland.gov states that the double-check valve assembly and the pressure vacuum breaker assembly are most commonly used in irrigation systems, while the National Fire Protection Association (NFPA) states that double-check valve assembly and the reduced pressure zone assembly backflow preventers are best for fire protection systems.

Ask a plumber for recommendations on the best backflow preventer device for your home.

Copper pipes are the safest type of pipe for carrying drinking water because they won't leach chemicals into your drinking water. However, for the best water quality, you should use copper pipes with lead-free joint material. The next best options for carrying drinking water are CPVC and PEX pipes.

If you use copper pipes for drinking water, you should check your water’s pH level. If it has a pH value lower than seven, you'll need to balance your water acidity with a purifier to avoid corrosion that could affect your drinking water quality. 

Your toilet will still flush if the septic tank is full, but it might flush more slowly. It may make gurgling sounds as the wastewater slowly drains through the pipes. You may also notice the toilet clogs up more frequently when the septic tank is full, although this can also be a sign of other plumbing issues, like a clog in the pipes.

Costs depend on sink type, labor, plumbing modifications, and whether additional fixtures need upgrading.
