Leaking in Backwash Hose

Leaking · Postby **Leaking** » Sun 15 Mar, 2009 23:06

I vaccumed my pool today and now water keeps running through my backwash hose... I have it switched back to filter but water keeps running through (but not much, just a steady, light stream)... i had to close the valves otherwise i would have created another pool

this has never been a problem before

I did have it on "recirc" for about a minute before i put it back on filter... not sure if i have a leak...? clearly, the filter is not closing off and water is leaking through at the "filter/waste/backwash/recirc/rinse" switch (whatever that is called

one more thing... I did do a backwash and went through those steps, thinking maybe the filter did not close cleanly... didn't help.

Any ideas?

The 6-way valve, or multiport valve, is not closing off the waste line. This is usually due to:

wear and tear of the spider gasket
scaling of the spider gasket
wear on the compression plate (rotor)
weakening of the compression spring

Generally the problem lies with the spider gasket, and replacing it solves the problem. Adding a valve to your waste line will stop the water loss, but may result in reduced or problematic filtration if the leak increases. Here are some pictures of a the spider gasket for multiport valves.

Thanks Larry

I figured that it had to do with waste, since I had not vacuumed to waste in a very long time...
