I went to Warehouse pool supply to purchase a new relief valve assembly for the Hayward Stainless Steel Micro Clear DE 720S. SUPRISE THEY DID NOT HAVE IT. I was told to contact Hayward since it was "obsolete". I contacted Hayward and they finally replies today AND the no longer manufacture those replacement parts due to the filter being obsolete AND they have two suggestions. One. buy a whole new DE filter system which means spend a bunch of money.
2. see if you can find a pool supplier on line or phone local pool suppliers to see if they have any Old parts sitting around. Other than the relief valve I wanted to replace because it keeps eating the o rings there is nothing wrong with the filter and We have replaced the grids with no problems. Has anyone else had problems getting parts for this Hayward filter?
