I'm new at this, so be kind please . I have to clean this filter NOW (1-2 week wait to have professional clean). Pressure too high not long after backwash (5 times in less than 2 days) & pool is gross after recent storms. My filter has a multiport valve, and the suction valve controls only main drain & skimmer (both skimmers on same side). It's a Never Lube Jandy Valve if that helps. I have gotten this far: I back washed the filter to decrease amount of DE & debris on filter, then cut the power. I have release the pressure, and removed the drain plug from the bottom. I'm not sure about the next step. I've read conflicting advice on the suction valve, but my manual states to turn it to 100% suction! which is what I've done (the "off" portion of the lever is over the main drain). Is this correct? Also, not sure where multiport valve should be positioned - on "backwash" or "closed"? I hope this is clear! I just want to make sure the pressure is gone before I remove the lid (I assume it is, as water drained from the bottom). Thanks for reading, & any help is appreciated!!
