I'm buying a Wayne 3/4 hp sump pump. I was looking at 1.5 inch check valves and was thinking about buying a Zoeller 30-0181 check valve. Is this a good choice or maybe there is something a bit better? I can spend up to around $30 but I would like to buy one that is quiet and that does not have a bad reputation.

Hey guys. I've got an issue with my water pressure. I filled most of our 6,500 gallon pool with water from our tap. Our water stopped running for a bit, so I turned off the hose that was filling the pool. After a little bit, the water came back, but the pressure is dismal. That was 3 days ago. The pressure is still really low. It's constant, but low. It's a drilled well, 90ft down. It was pretty dry for a few days before and while filling the pool, but we had a good rain yesterday. I checked the basement for leaks, found nothing. I can hear the pump running in the well. And the filters are running downstairs. Any thoughts on what could be causing the low pressure? I was thinking either there's a leak in the main line, the pump is (half) fried, or the filter is clogged. We have a pot perm filter by the way.
