Hi I'm posting here instead of the AG category because this applies to all pools. My backwash hose has water coming out slowly when the pump is on filter. I want to remove the multiport valve and check the spider gasket but there is no air release valve anywhere that I can see. How do I remove any built up pressure so I can take the valve off safely?
The filter is a 100lb Hayward Hi Rate Sand Filter with a Vari Flo XL valve. Thank you.
