What is a Hydrostatic Test?

July 2, 2020 | Blog

No one wants a leaking sewer pipe. However, sometimes it’s unavoidable. As a homeowner, it’s important to know when plumbing leaks occur in order to avoid prolonged water damage and high repair costs. Therefore, if a leak is suspected, a plumber will sometimes perform what’s known as a hydrostatic test – a water pressure test used to detect leaks in a home’s plumbing system.

How is a hydrostatic test performed?

This type of test is done by first locating a home’s mainline sewer cleanout. Once the cleanout is located, a plumber will insert an inflatable ball. They will then inflate the ball to plug the sewer line under your home.

While the line is blocked, the plumber will begin to fill the sewer system with water until the water is level with the edge of your home’s slab foundation. After this, the water level will be monitored for about 15 minutes.

If during the 15 minutes, the water refuses to fill up to your home’s slab level or if the water’s surface level begins to drop, chances are you have a leak in your plumbing system that’s in need of repair.

When should a hydrostatic test be done?

Sewer line leaks can be caused by external factors like tree root intrusion, old pipes and shifting soil. Static test plumbing should be used for leak detection whenever you notice unusual changes in your home’s plumbing. Leaking pipes under your home may lead to any of the following issues:

  • Cracks in your home’s foundation
  • Higher water bills
  • Unpleasant odors
  • Damp flooring or carpeting
  • Mold growth
  • Septic waste pools in your yard

If left uncorrected, leaking sewer pipes can cause major damage to your home’s foundation and plumbing system – so it’s important to have a hydrostatic test done as soon as you suspect a leak.

If you think there may be a leak under your home and are in need of a static test in Boerne or San Antonio, contact Parker & Sons Plumbing today for an expert consultation on leak detection and repair.

I recently had several plumbing leaks repaired and couldn’t be happier with the prompt service I received from Parker and Sons. They are very knowledgeable, friendly, reasonably priced, and do quality work. I would definitely recommend them to my family and everyone. I would trust them to repair any leak in the house.

Amazing Service!!!

Amazing service!!! Called and came the same day within 2 hrs. Our toilet had to be re-fitted and snaked. They did a beautiful job on the re-fitting and got the large piece of plastic out of the toilet. Will definitely be recommending them to friends and family. Great service, great people, hard to find these days!!!

Brad B.

Great to Work With

Jim and his guys are great to work with. Had Parker & Sons come out to take a look at an AC unit at one of my rental properties. Unit is in the attic. Had to replace a coil on it and did a great job. Will definitely use again.

Jeff C.

Amazing Staff!

I have referred Parker and Sons to all of my customers and I would not think of referring anybody else. They have been great and very punctual. All of the plumbers and office staff have been amazing!

Miguel B.

Reasonable Prices

I was in good hands today with journeyman plumber Mark Rizley. He remained until all was better than before. He replaced a PRV and improved a mediocre repair recently done by another well known local company. The price remained reasonable despite the extra effort needed for the job. Well done Mark! Parker and Sons will be my first call in the future.

Todd D.

Fantastic Company!

This is a fantastic company with outstanding professionalism, quality of work, and customer service. While their prices are extremely competitive, their work doesn’t feel cheap like some of the companies you can hire of off Craigslist or on a FB yard sale page. This is a reputable company with proven work and licensed, skilled technicians.

Fair Prices & Excellent Work

Have used Parker & Sons 3 different times, once for a huge complex plumbing repair and twice for smaller jobs. Fair prices and excellent work/fast response time every time.
