just want to give an update to close this off - Hayward is sending a new MPV. They didn't ask any questions or ask for any evidence of the problem, so I'm guessing they've seen this problem before.

yes, the two flats are lined up

hi, I'm sure MPV and filter are compatible; the MPV part number is listed in the filter owner's manual. But for completeness, pictures are attached. @Mdragger, thanks and yes, next step is to contact Hayward. I just wanted to make sure this leak was unexpected before calling them.

thanks for all the answers

Just following manufacturer's recommendations. Should it not be done?

I've got an RJ60+, and will be cleaning it soon. Once done, I'm planning to dump the acid from the cleaning back into the pool, since I'm always adding acid anyway. Is anyone aware if there's any reason not to do this? Maybe I'm being paranoid - as far as I know, it's only dissolving calcium...
