Hydrostatic Valve Replacement for your Swimming Pool

Aqualine Pool Resurfacing recommends all swimming pool owners consider the age of their pool's Hydrostatic valve when their swimming pool first starts to leak.  It should be your first line of attack before obtaining expensive pipe pressure testing and leak detection services.

In most cases, pool water leaks are  caused by old worn out Hydrostatic valves.    

Hydrostatic valves are relatively inexpensive to replace.  In fact the Hydrostatic valve, in your pool, should be replaced every five years to ensure you have a good seal and your swimming pool is not losing water. 

Aqualine Pool Resurfacing can replace your Hydrostatic valve whether your pool is full or empty.

How the Hydrostatic Valve Works

The Hydrostatic relief valve is located in the deepest part of your swimming pool.  It may be under the main drain cover or in its own box situated on the bottom of the swimming pool.

The purpose of the Hydrostatic relief valve is to act as a one way valve allowing water into the pool but not out of the pool.  It opens when there is an excessive build up of water pressure under your pool  This allows the ground water to enter the pool and keep the equilibrium between the pool and underground water to avoid damage to the pool.

Most Main Drain assemblies are designed with the same major components.

• The Grate and Dress ring sits in the tile or marblite on the floor while the remainder of the Main Drain assembly is cast in to the concrete of the floor.   
• The Dress Ring does not have to touch the body of the main drain.  
• The Main Drain must be installed at the deepest point of the swimming pool so the water is able to drain completely from the swimming pool.  
• The connection to the skimmer allows for a certain amount of water to flow naturally from the bottom of the swimming pool in to the skimmer.  
• The valve stem protrudes into the gravel pit below the structure of the pool so the water can drain into the pool easily.  
• The hydrostatic valve is flitted into the base of the drain to stop water going out but allowing high pressure water in so the pool does not lift out of the ground.
