The flow tubes inside the filter canister are torn and letting dirt pass. The repair is simple and can be done by someone with a few hand tools. Download the manual for the filter here:www.haywardnet.com/products/Manuals/pdfs/manual9.pdf

You'll only need to replace the ones that are ripped, and the cost runs about $3 - $5 each. Search around on Google for a supplier or try a local pool dealer.

check your pool pump by putting the valve in recirculate mode.If flow is a problem it may be a clogged impeller.

There is more than one version of these valves. The model like sp072 has a 5 spoke spider gasket that has one opening larger than the rest. Be sure it is in position so that the large opening lines up with the large opening in the valve. If it's a SP0714 then the rubber is molded on the valve itself and would have to be replaced together. In either case, the seal is provided by the spring pressure forcing the valve faces together. That is why you should depress the handle, and only turn the valve while it's depressed, and the pump is off. After you turn to the selected location, then you release handle, and the valve surfaces should spring back together. Be sure the lever has spring tension on it in case you left it out while working on it) You can download complete manuals from www.haywardnet.com Good luck!
