Re: Don't know what I'm doing. Need help with lack of pressu
Sure sounds like it may be something with that multiport. I see some concrete block wall in the pic. Is this setup inside or is it in an area where you can run some water? I would disconnect both of those unions going in and out of the filter. Maybe you could run a backwash hose or some other temp setup back to the pool so you don't loose water. If not it may be worth losing some to do some troubleshooting. Turn on the pump. Is water flowing ok from the pump output union? If so where is it coming from - skimmers, bottom drain or both? If everything is working at this point you have eliminated the whole suction side and pump. Now connect to the multiport. What happens now? Try the multiport in all its positions. If it doesn't work now it's your multiport or filter. If it's still working connect your second union which is your returns. If the problem comes back now you have a problem with your return lines. This will at least get you working on the problem area rather than taking apart possibly good valves and snaking out and pouring stuff possibly good lines.
