Had many pools but this issue has me stumped.
I have gone and bought a whole new filter head for the sand barrel. Yet when I turn it onto filter I am getting waste gate open at a decent amount. I upgraded the pump to 2 HP and I am reusing the cotton ball filters I purchased last spring that worked wonders vs sand and they came clean in the wash. My buddy and I replumed but didn't change any sizes of pipe. I first replaced the gasket then replaced just the head with the handle to the gasket and today I received the entire head unit and it's still doing the same thing bypassing to waste while filtering as well.

The valve or spider gasket is broke.
