I just spent the entire weekend replacing the head. I bought I Jabsco compact toilet (I know, I just read on archived posts that Jabscos are bad...too late).Anyway, i am using 1.5" hoses as the instructions say, with double clamps. I connected a new hose to the old hose with a spacer (there was no way I could reach the y-connection to take the old hose completely off.The instructions say not to use sealant, but the leaks occur at all the fitting points (at the discharge elbow, on the spacer., etc.) Can I use silicone sealant? Am I using hoses that are too big, even though I am following instructions. Help. I am very frustrated.I followed all instructions.
