![]() I am pleased to see that Hayward has continued to improve their already great DE filter product line. Having just encountered a particularly heavy accumulation of oak pollen and blosom debris that indicated a need to manually clean the filter elements (rather than the more usual backwash routine) I was most impressed with Hayward's changes to the design of the clamp ring and the relative ease and speed with which the top shell and the internal filter elements could be removed. Upon first use, I found welcome improvements had been made to the ease of operating the air relief valve and to the pressure gage with a simple means for indicating changes in pressure from the initial setting and when filter cleaning is required. I recently purchased a Hayward DE-3620 filter as a replacement for a 10-yr old Hayward DE-3600, and was initially most satisfied with the ability to directly install the new unit in place of the old one without having to make any adjustments whatsoever to the interface connections with the existing vari-flow valve and external piping.
