What size pipe do you use, and how do you connect it? Is there a size that you can simply clamp the normal flexible hose around? you use standard Sch40 1 1/2" PVC and fittings. The end to take the hose can be had in the proper size from SeaLand, who sells a hose they claim (but which Peggie disagrees with) is superior to their prior OdorSafePlus, sells PVC end fittings. However, I just used barbed screw-in (to a pipe thread coupler) fittings which I ground down to fit properly. Better yet, I've learned (too late for the forward head) that you can use a rubber coupling, flush fit, to whatever fitting you're using (1.5" pipe and the barb described, but with a collar of 1.5" hose, which makes it identical in size to the PVC). Three clamps - one each at the ends, and one at the joint. The joint is contained in the clamp in the middle, making any odor products have nearly an impossible (I'm saying nearly because I don't have 5 years' experience to back up my expectation of NO) chance of getting to the rubber exterior. I've got that setup (flush - pardon the expression - rubber coupling) at the head and at the through hull on the aft. All that's to stop any future odor issues... Hope that Helped... I think so ... thanks |
