Sand Filter Draining When In "Filter" Position
Thanks for the question The question didn't mention a general leak, just that the sand filter is losing water, so we'll start from there. There could be many reasons why a sand filter leaks, but we'll start with the obvious. Check the air bleeder valve and make sure it's seated correctly. There might be an O-ring on it. You can take the valve out and inspect it. Change the O-ring if damaged or broken. Check the top of the filter for leaks. A bad O-ring might be the problem. Depending on what kind of sand filter you have, you can check the bulk heads. This is where the water goes in and out of the filter. They're called the "Influent" and "Effluent". Water in and water out. Look around the ground for wet spots. You may find the leak problem with that. Your Multiport valve might be the problem. You can check the O-ring and replace that if needed. If the valve is bad, replace it. Switch to another valve position. The valve should "click" into place. If it doesn't, you might need to replace it. Check the pool pump O-ring and replace that if needed. If this doesn't help you can email back with more details so I can help a bit better. Good luck Robert |
