Hayward sand filter multiport is making a hissing sound

[ulrichsd]

On the "filter" setting it is making a hissing sound and the heater read low pressure. When I backwash, the flow coming out is much lower as well. I've been backwashing frequently (2-3 times a week, since I have a slide hooked up to a hose that is causing the water level to rise). When I turn the filter to recirculate (bypassing the filter), the hissing goes away and the heater low pressure light turns off. So I'm running it on recirculate for the moment.

Do the multiport gasket heads eventually wear out? I've moved here 6 years ago so I have no idea how old this thing is...

Thanks!

Do the multiport gasket heads eventually wear out?

Yes they do! Go to inyopools.com and look for your replacement part. Also buy some silicone lube, your equipment seals will need it regularly.
