I winterized, including pouring pink stuff down all the drains but evidently had enough untreated water just behind the grey cutoff valve to freeze and crack the pipe. There is a crack in the 1 1/2" ABS sweep 90 degree ell pipe. That sweep ell is glued to the Gate valve. I can get a new sweep 90 degree ell at any plumbing shop but because it's glued to one side of the grey gate valve, I'll need to replace part of that valve body too. My question is this. I have the combo black 3" and grey 11/2" dump setup as most RVs. Can I purchase a standard 1 1/2 gate valve and remove the side that "I need" to replace and bolt it back together and have any success? Or do I need to figure out and buy the same brand? I'm trying to buy the $15 gate valve and only use the,1/2 I need rather than buying the $45 combo unit and using only a 1/4 of it. Any thoughts?
