90 degree elbo & A New *&^%$ Waste Hose

[Grizz]

Time for THE expert's advise while fielding a few questions. The OEM discharge fitting at the holding tank for the 1.5" waste discharge hose has a 90 degree elbo oriented at a 2 o'clock position. A PO (unsure which) had filed down the hose barbs to make it easier to mount the hose. I now understand why: Houdini would have difficulty getting leverage to slide the hose onto the barbs.I've tried soap, a hair dryer & soap, colorful language, louder colorful language...all w/o success. Now I'm hoping you have a secret solution. Or maybe an answer to (2) simple (if dumb) questions: 1) Is there a need for the 90 elbo? 2) Is there a reason to not use a straight fitting? ( I may have just enough leverage, grip and access to get the hose connected with this fitting).Everything but this line is connected and ready for Spring Splash. This isn't 'mandatory' but certainly falls within the 'Nice To Have' category.Thanks for any guidance you may have to offer. Now I'm off to find my wife to explain why I'm e-mailing the Head Mistress. Sometimes you can't win for losing...Take care.

I understand...whew, what a job

No reason not to make it straight. Heck, where's it eventually going?

Sealand

Sealand has some black connectors which don't have barbs on them . Far easier to work with. RD

A few quick comments

The final direction of the hose should dictate whether you need a right angle or can use a straight barb. As a rule, avoid using 90 degree angles as they are more prone to clogging. In fact, use the fewer connections (reducers, adapters, y-valve, etc). As for "the trick" to dealing with the hose. First, I only use plastic hose barbs with the plastic fittings in the tank (and metal with metal). The threads mate better and it makes me feel better in a cosmic sense. Second, buy the good somewhat expensive white waste hose from West Marine. Not the really expensive $7/ft but the $3/ft type. Cut the hose to the proper length with a box cutter. Put the ends of the hose in some boiling water or use a heat gun / hairdryer to enlarge the ends. The hose should now go on easily as long as the barbs aren't too pronounced. Otherwise consider grinding down the barbs with a dremel and /or putting shampoo on the barbs and the ends of the hose. Hope this helps.

a

1) Use a 90 degree elbow if you must but use as few fittings as possible as they are clog points2) Use white $3/ft waste hose as sold at west marine3) Cut the hose to length4) Enlarge the ends of the hose by putting them in boiling water or heating them with a heatgun / hairdryer.5) Shove the ends on while the hose is still hot. Use shampoos to lube the hose if you mustThe white hose might be more expensive but it is easier to use than the others and has better odor fighting properties.Good luck.

Thanks..

...for the responses! Looks like I'll be scrapping the gray PVC for nylon/marelon and pre-soaking in really, hot water (hose already in place, no way to boil) and swapping out the 90for a straight. And then the head will be back in business!Thanks again. Take care.

Use a blow dryer to warm the hoses.

And K-Y jelly to lubricate both the hose and the fitting. Do not use any sealant...only a Teflon tape on any threaded connections. Double clamp all connections, with the screws on opposite sides of the hose...or at least 90 degrees apart if you don't have access to tighten one that's 180 degrees.Btw...warming a hose first also makes it a lot easier to get off a fitting.

Very hard to assemble!

I used the grey (schedule 80?) pipe for re-plumbing my waste tank recently. I used solid PVC where ever waste would be standing in the hose between pumpouts with sections of regular waste hose to allow flex.I did have to assemble the hose to the PVC in my workshop using a vise, and all the strength of myself and my wife (with heat and soap too). I didn't actually realize that the grey pipe was a slightly different size! It will never come apart though!!!Chris
