Multiport Valve Is Stuck In Backwash Mode
Do I need to remove the top of the valve and reposition the port? Thanks for the question Your swimming pool pump and filter are the most important part of your system. Next is the multiport valve. This is what you can do if you're having a hard time rotating the multiport valve: 1. Remove the pin holding the handle to the stem. 2. When the handle comes off, you can unscrew the bolts on the lid. 3. Remove the key stem from the cover There should be a small O-ring on the shaft. 4. You should see a spring. This spring holds the key stem down on the spoke gasket. Replace the O-ring if it's worn or split and clean the shaft, spring, and the hole of the cover. 5. Lube the O-ring with Aqualube or something similar. Don't use regular Vaseline. It breaks down quickly in water. 6. Put the key stem back in the valve with the hole in it. You want to go towards the filter tank for a sand filter and the hole away from the tank for DE filters. 7. Put the spring and washers (if there were some) back on the key stem. 8. Put the cover back on with the filter position over the opening in the key stem. Tighten down the screws/bolts using a cross pattern. Be sure to check the O-ring to see if it's seated correctly. 9. The handle should go on in the "FILTER" position. You can replace the pin that holds it on. Remember this is for information purposes only. If you're unsure of the directions above, please call a professional pool tech. Hope this helps and good luck with your valve. Robert |
