Sand Filter Issues

[BigDave]

I would make sure the borwn stuff (sand?) doesn't go through the solar loop.
I have a 1/2 hp pump that's rated at 40GPM...your filter may be too small. Do you have a valve that you could use to throttle the flow?

I'm not sure but could it be you didn't wash the sand first? Did you backwash before you set it to filter on start up? how about your multiport is the o ring and the spider gasket in good shape?

I backwashed the filter before using it, but I think that I should have possibly rinsed it longer before putting it into service. The sand flow has diminished to almost nothing after a couple of weeks. I believe that the o-ring and or the spider gasket could be bad because I have to fiddle with the lever every time I move it to stop it from leaking. The unit is quite old and I'm having trouble finding a clear replacement. I hate to tear it apart until I am sure I have the right parts.

I do have a ball valve in the return line that I use to throttle the flow down some.

Thanks for the responses guys!
