I believe the pipe between my skimmer and the pump is clogged. I had my pool repair guy out yesterday and he tried everything to dislodge it but couldn't. He tested the pump and the power supply to it but they were fine. Water will flow into the pump but very little. He suggested I try filling the pipe with Muriatic Acid which I have done but it is not working. It has been sitting in the pipe since last night but the level of acid has only dropped a small amount indicating that it is just sitting at the debris that is clogging the pipe. Should I continue to wait for the acid to break down the debris or do you have any ideas?
