Swimming Pool Property Management

It's the time of year when owners and tenants start wanting to use their swimming pools. And this means that property management departments of real estate agencies have to respond quickly to problems. The main problem seems to be leaking pools, and most people assume it's leaking pipework. A good clue for this is bubbles in the return water flow.
But a leaking hydrostatic valve is another common problem, that Ray White Beecroft has just rectified with one of their rental properties.
http://www.aqualinepoolresurfacing.com.au/Hydrostatic_Valve.html provides an excellent article on this - "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 50% of cases most of the water is being lost from the old worn out Hydrostatic valve."
I wouldn't agree with the 50% statement, we have had many more proven leaking pipes, but the point Aqualine make is still valid. And remember, never empty a pool negligently! If the hydrostatic valve fails, external water pressure can push the pool out of the ground!
