Plumbing tip needed!

[Boondocker]

I am having fits trying to attach 1 1/2 in spa tubing to a barbed fitting. The spa tubing is just a tad too small to get onto the the barbs. I tried heating the tubing in hot water thinking that would help it stretch some but this had the effect of making the tubing to pliable to push on. I know there has to be a trick to this, someone help me out here. Thanks!

Since the male fitting is barbed, soap both surfaces with diluted dishwashing soap after warming the hose.

NOT dishWASHER detergent.

It will work. Perhaps you overheated the hose.

On the other hand, you may have simply bought the wrong matching hose or fitting.

I saw Lewster checking this thread. While he doesn't post anymore, I will bet he would answer a PM should you send him one. He strikes me as willing to impart useful advice.

I am so sick of this plumbing crap. Why the *&%$ everything of a given size wont fit everything else is a mystery to me. The sewer outflow from the black tank is 3 inch of schedule something or other and wont fit the other schedule something other (still 3 inch) that the new sewer fitting is. Inch and a half spa hose doesn't go on an inch and a half fitting. Talk about BS. You shouldn't need a decoder ring to make this stuff work. Makes me sick of the camper, and I do mean fed up.

If it is true spa hose pvc,it will glue into a 11/2 pvc sch 40 fitting,if your barb is by male,buy a 1 1/2 male adapter,screw it into the female then glue the joint. Dave

I wonder what would happen if I took my Dremel tool and cut a small grove in the male fitting so it could compress a bit and allow the spa hose to go on.

Might work cut at least 3 slices soap up really really good so it will keep going past the slits

Gen,

Take an razor or Exacto knife and bevel the tubing on the inside about a 1/4 inch into the tubeing Lube with your favorite lube (soap) and push. Also - insert the barb fitting into a pipe union and screw on a pipe extension of about 6 inches - gives you much more surface to grip than the small fitting alone.

been there - done that - screamed my head off - nobody heard me, I was under a house................

I went back out this morning fortified with a nights sleep and foolish optimism. I found a couple other fittings I had and sure enough the barbed section of the fitting I was working on was noticeably larger in diameter than the others. Is the plumbing industry the last one on the planet to catch on to industry wide standardization?

With the use of boiling water to heat the hose, a pair of tin snips to stretch the heated hose from the inside, some dish soap to make everything hard to hold onto, and a pair of channel locks to force the spa tubing over the barbs, the tubing finally went into place.

I don't think anything would have gotten the original fitting to work. To all members of the plumbing industry: if I have posted anything in this thread that hurt your feelings, I would like to extend to you an completely sincere and heartfelt middle finger.

I wish I had been there with my camera.

Thanks for the followup - I am glad your plumbing is now connected.

Hopefully, you will not need to dissassemble it anytime soon...

Chill the barbed fitting in the freezer, warm and lube the hose.

Rodney,
Chill the beer mug in the freezer, warm and lube your feet, pour the beer, enjoy the moment -- Way to stay with it.

I went through similar last year in Canada with propane gas hose for old Primus campstove. Took three days of going back and trying again. Heated one thing, chilled another, almost cut my hands off. Finally got it.

And ditto on your New Yorker salute for those industry standards promulgators.

Best,
Jim
