Water Savings And A Common But Costly Leak

Whilst we have been enjoying some rain this winter, and the dams are above 50%, the end of water restrictions pertaining to pool owners is not something that will be changed anytime soon.

With summer just around the corner, we need to be sure that we are still doing all we can to save as much water as possible, to ensure that come summer, our pools are crystal clear and blue.

Most pool owners will by now have implemented some form of water saving device into their pool system. If not, now is the time. Some examples of water saving devices and system are

  • Covers
  • Liquid-based cover
  • Backwash tanks
  • Glass filter media
  • Cyclonic pre-filters
  • Boreholes and well points
  • Robotic pool cleaners

If you do not have one of the above-mentioned systems, then be sure to contact us and we will guide you through the most suitable options for you.

All the above-mentioned systems work really well but can be easily undermined by a common unseen and simple leak, and that is a worn MPV gasket. With most pools having covers, the gradual drop in water level may go unnoticed.

The MPV or multi-port top is the handle you change from the filter to backwash and rinse.

A worn MPV top and gasket will allow water to passively leak out the backwash pipe, even when the system is on the filter. So for 10 to 12 hours a day, there will be a slow but persistent leak.

To ascertain whether the MPV is leaking, you can do the following:

You can either check the backwash pipe when the system is on. There should be no water coming out of that pipe at all.

The other way, if you are not able to see where your backwash water comes out, is to remove the plastic sight glass, located on the back of the MPV housing. There should also not be any water coming out of sight glass housing.

This very simple 5-minute check could save you thousands of liters of water.
