I will start off by saying i am new to the world of pool pumps and issues, so i may not use the correct wording. This issue is on my parents pool but i am an engineer so i am semi-capable with fixing issues.
The pool was opened after being closed all winter. Everything was working ok and then we vacuumed the pool and it has not really worked since then. We have a Doheny's self priming pool pump that was replaced last year and a Pentair DE filter. When put in the recirculation mode the water comes in from the skimmer into the strainer basket on the pump, but never reaches the top and bubbles can be seen. Water comes out of the return lines slowly and with bubbles.
When put in filter mode, water does not fill up the filter and very little pressure (1-2psi) can be seen.
items done to try and fix the issue:

items done to try and fix the issue:
- spider gasket on the filter valve was replaced
- drain king was purchased and used on the intake line from skimmer to strainer basket. no blockage was found
- when a hose was put into the line the water was able to fill up the strainer basket more- however air bubbles still seen coming out of the return line
- since issue is seen on recirculation too- i would guess it is not an issue with the filter
- housing top for strainer basket does not appear to have any leaks or cracks. relubed the o-ring recently
- ran water over the top and it did not fill the basket any more than was previously in there
