I have an AquaTools filter that is approximately 10 yrs old. I had a leak from the backwash. I replaced it with a Hayward spider gasket but the gasket seemed a bit small and water is still leaking out. I also removed the handle prior to removing the multiport valve and now there is now it is extremely difficult to move the handle which flops up and down.

SOURCE: I installed a new pentair de filter and new

If the pressure is 15 psi on recirculate, and high on filter, the problem is the filter itself, or the valve plumbing. The DE filters are unusal in the fact that they are plumbed like a sand filter, NOT the cartridge filter. If you could give details as to which filter AND multiport valve you have (look on sticker for model number on valve) it would help to figure out if the problem is in the filter or valve.

SOURCE: Water still flowing out waste when filter is in filter mode.

You proberly have sand traped in handle shaft above spider gaskit.

It is best to take apart - clean - grease (pool grease) - put back together.

When backwashing (or moving handle to other postion)- let pressure build up escape before moving handle to next position.

SOURCE: I'm hearing air like sounds

Air only gets into the lines of your equipment if it enters somewhere on the suction side of the system. That means from the pump housing and strainer BACK to the pool on the inlets. Once the water passes from the impeller out the discharge of the pump it is under pressure and any leaks will result in water escaping from the line.

While your filter may or may not need work air is likely the result of failing gaskets or a seal in the pump. Replace the strainer lid ring, the pump body ring and the mechanical seal first. If there is still air look at the valve or valves in front of the pump for controlling inlet water flow...check for leaking stems or failing pipe joints.
