Hi, first post, new forum, but you guys seem knowledgeable, and so I need a bit of help.
A little background, the pool is a 22,000 gallon, 1.5HP 2 speed pump, Hayward C4000 cartridge filter (425^2 ft.), and a Pentair Heater. The pool works great, easy maintenance. Its 16 years old. I've gradually become adept at doing all the work myself, and I've replaced all of the system (pump, heater, polaris, motors) as I've learned the ins-and-outs of maintenance, so none of this is quite new.
I realized that Hayward no longer made some of the critical parts for the existing filter, and to avoid downtime I decided to replace/upgrade the filter. After doing some measuring, I realized that a Hayward C series seems to use identical fittings, and just as important, the inlet/outlet are exactly the same height as the existing filter. So I chose a C5030, which is a bit bigger (525^2 ft), and it arrived today.
I realized that in looking at the connectors, I have no idea how they work, and there are basically no instructions to speak of. The instructions are here: http://www.hayward-pool.com/pdf/manuals ... -C7000.pdf
So my question is...these fittings look like they screw into place, but (a) how do they install on the filter body and (b) do they glue onto the PVC?.
Ideally, I'd like to unscrew the existing two connections and screw them onto the new filter, but now I'm not sure that plan is feasible.
Any comments or instructions you could provide would be appreciated.
