I built a pool (with a lil help from tfp) and the deck around it myself last year. Bought a new heyward pump and de filter and everything worked great for the season with minimal aggravation. fast forward to yesterday, i lugged all the equipment out of the garage, took pump apart and checked impeller, looked good. took filter apart and hosed down d.e. fingers, looked good. plumb everything together with pvc exactly as it was last year, turn everything on, add 7 pounds of d.e. Success, I'm ready for summer!
10 minutes later my filter pressure gauge that was reading 10 is now 25 and there's barely any push on the water returning to the pool. checked all fittings for leaks, all dry. bumped filter a whole buncha times, thought that may have solved the problem as pressure returned and gauge read normal. 10 minutes later, same problem. i feel like i'm missing something simple. any ideas?
