HydroStatic Tests

It’s a common plumbing or drainage test performed used to determine if there are leaks in a structure’s drainage system. 

As part of the static pressure test process, the sanitary drain piping under a structure is temporarily plugged which fills the system with water. The water level is then monitored for up to as long as 20 minutes in order to see if it drops. If your structure fails the plumbing test, this means that your water level did drop and you have plumbing leaks in your foundation that need to be repaired. 

Most people get hydrostatic test done before buying new home, to make sure house isn't leaking

Isolation Tests

Once your home fails a hydrostatic tests, the next step is to perform an isolation test to see where exactly you have a leak.

​These tests require re-setting a commode to observe the water level during testing. The general idea is to systematically check for leaks by isolating each restroom and plumbing fixture one at a time from the rest of the structure. Through a process of elimination, the plumber will be able to determine where the plumbing leak is and stop it before it further damages your foundation. 

How to tell if your home needs a hydrostatic test and possible reroute.

While some leaks in house foundations are difficult to see or detect, here is a list of eight things you should take note of:

  1.  Damp carpeting, discolored flooring, wet linoleum or little bubbles coming up from the floor. When water leaks, the only direction it can go is up. This means that it will rise to the surface and you may start noticing that your flooring that is moist. 
  2. The sound of running water somewhere in the house. If you suspect a leak, listen carefully, it could be harming your foundation.  
  3.  A warm floor in one area of the house. Because hot water leaks generally occur first, this could mean that your hot water line is leaking and water is coming up through the foundation. 
  4.  Foundation cracks or cracks in walls or flooring could indicate foundation damage caused by water leaks.
  5. If the water in your pool is consistently low even though you keep refilling it.
  6.  A sudden loss of water pressure could indicate a link in the main water line.
  7. Unusually large water bills are a classic sign of trouble. A plumbing leak that is absolutely tiny can create a 10,000 gallon water loss in a period of one month.
  8. Observe changes in your water meter. If the leak detector inside your water meter keeps spinning, that’s an indication of trouble that could impact your cracked house foundation. Another way to check it is to turn off all the water in your house and read your meter. Then, about 30 minutes later, turn the water back on. If your meter reading is higher than it was when you first checked it it's time to call us.
