Low Pressure

You probably have a restriction somewhere between the impeller and the skimmer. Low pressure is indicative of something blocking the water coming from the pool to the pump. If that portion of your system is unblocked, the problem is most likely right at the impeller.

When our pressure was about 1/2 what it normally is, my husband thought we might need new sand because ours looked gooey. And in the process of changing that, he broke off 2 of the laterals. So we had to order those. After a 2 week wait, they finally come. So he puts it all back together including new sand, but the pressure was still low. Then he decides to try a new gauge. That of course wasn't the problem either. When he starts panicking that we have a leak underground somewhere, I convince him to call the pool store. It ended up that all that was wrong was a lost gasket in the pump. I have no idea how it got off, or where it went, but that's all that was wrong.

In our case it would have been faster and cheaper just to have called the expert in the first place.
