| Those new diaphram housing look like a really nice alternative to chasing down a set of good used units or purchasing new. Did you take any pictures of what the inside of the housing and spring conditions were? The diaphram looks like it's in pretty good condition, did you test the original spring and compare it to the new? Did you do a functional test of the valves to see where they opened at before & after installation? Are there replacement diaphrams included in the kit? Are there a range of different springs available for adjustment of opening pressures?
