Her pool guy told her the push-pull valve on filter was stuck. He did not do repairs and told her to find a swimming pool repair company.
Solutions provided:
We found the backwash valve internal assembly needed to be replaced, which we did. We also noted DE in the pool. She approved a filter clean and found there were bad grids and the top filter manifold was bad. We replaced three grids, the manifold, re-assembled the DE filter and the pool is again clean and clear.
