luey123 Posted October 6, 2014 Report Share Posted October 6, 2014 I'm going crazy with having cracked and ruined the threaded pipe fittings on TWO Hayward C-250 filter housings while trying to plumb them. First issue could have been teflon tape but Hayward doesn't say not to use it and I was cautious about overwrapping and/or over tightening. The second time around with NEW FILTER I used Rectorseal 5 as per extensive research (Bowy it's a jungle out there on sealants and opinions!) and I can't even tighten beyond hand tight before the filter fitting starts fracturing in very very fine hairline cracks. I am suspecting some kind of thread variation or PVC differences but to my knowledge am doing everything right. I am shocked at the ease I was screwing the pipe in BY HAND with no sign of reaching "home" when the damn thing split... in numerous places!! aaarrrrggggghhhhhh!!!! Ive asked the dealer to contact Hayward but I have gotten much more help here if anyone has advice. Thanks. Quote Link to comment Share on other sites More sharing options...
