Hello all. Need some help. Having a nightmare time trying to get my pool running this season just to get by until next season when I am replacing everything. So I have a Hayward DE filter with multiport valve. The gasket has been messed up so I glued it down with some superglue yes superglue lol just to get it down. The backwash pipe is not leaking at all and I dont even care if it gets a slow drip or leak this season. Filter kicks in, jets start flowing and skimmers circulating but then within 15 minutes my PSI shoots up to 25 psi. I backwashed, rinse etx no help. So then I broke down the filter and it was a good amount of dirt grit but a few of the grids had tears in the top where they are stitched. I dont know if the high pressure ripped them or they were ripped. So I am gonna replace the few grids Saturday but my gut is the pressure wont be resolved unless I get lucky. Could the multiport valve even if the filter is running and jets start to work could it be causing if not right the high pressure? I know it cause a leak but the pressure I am wondering. tx all.
