Hello! I am new to the forum - I have an I ground pool (Ester Williams) that was put in, in 1961. The pump works, the sand filter works (we changed out the sand) but the skimmer does not have any suction. I thought the pipe was clogged as it had been 9 years since we last opened the pool. I have put a snake down the pipe (from the filter to the skimmer) and used a wet vac to suck out anything that may be clogging the pipe from the skimmer. However, nothing came out of the pipe. I cleaned out the basket to the skimmer, the basket in the pump and backwashing works just fine as well. Other than taking out the concrete to visually inspect the pipe, what should I do?
