OK I guess I have half the battle done, found small leak now need repair advice. The is a PVC manifold under the recliner portion of tub with six vinyl hoses attached, it appears that one or two may be leaking slowly, I tried to add some radiator clamps but they didn't stop leak. If I cut the hose then it would be too short to reattach and I don't wanna have to trace it back to source. Is there some type of connector type connection(to extend length), and what is neccessary to reattach to manifold and prevent leaks.
BTW this is a Vita spa with full foam insulation. Thnaks for any and all help.

You betcha! I've done this one myself a few times with great success. My guess is that you discovered that the clear vinyl pvc hose has enlarged around the fitting? What I did in this situation is cleared the insulation from the clear pvc hose so I had about 6 inches to work with. then I cut the enlarged end off all together. Then about 2 1/2" back from the cut end, I cut it again. Took that hose to the local "Home Depot" and got a brass compression splice fitting that fit my hose. I used that to put in the place of the cut I made 2 1/2" back, and had enough hose to slip on the barb of the manifold, since the compression fitting adds about an inch, and used the hose clamp to be sure it stayed in place. If you aren't sure if you will have enough, "Home Depot" sells this clear hose in rolls, so then you have all you need.

Thanks Charger!
You got that all right, I already have enough room to work the hose,although its always gonna be tight in there. I understand what you are saying, sounds fairly straightforward. Would you use any kinda glue or sealant on the manifold port? It kinda got me worried about all the other manifold fittings around the whole tub. Thanks again for your work on this forum. What would we do w/o the internet? Proceed Blindly.

I wouldn't use any form of sealant, as the manifolds are easy to break, and if you have to ever remove that hose again, trying to undo sealint will greatly increase the chance of it breaking. I would just use a stainless hose clamp and call it good. Just don't over tighten them... snug is usually enough.

hi Charger,

went to home depot, was not quite sure about compression fittings. I know about comp fittings for copper tube, but they had some plastic type compression fittings also, are these the ones you mean?they went up to 1/2" in sizeat that store. as usual HD personnel were useless.

You still use the copper compression fittings. What you do is the fitting should come with two brass furrles that are basically inserts that you put inside the pvc/vinyl tube, so when you tighten down the fitting, the compression ring clamps against the furrle, thus locking the hose into place. You don't need as much torque with the pvc/vinyl tube as you would copper, of course! I will attach a picture of one to show you what I am talking about. It's a little blury, but I think you will get the idea.

Charger,

Thanks, great pic I have seen those and now know exactly what to do. I can't believe the Home depot personnel, they had no clue.. Thanks, Ira

Hi Charger,

I went to H/D and called around the plumbing supply houses, no one has compression fittings for the 3/4' ID vinyl. Were you talking about some smaller diameter? I called manufacturer (DM Industries) and spoke with tech, he told me to get the plastic barbs to extend the vinyl hose and use PVC cement on the fitting. Whatta you think? Thanks again.

The barbs would work fine, and I would use hose clamps on them as well to be sure a good secure fit. I'm still not shure I would go and cement the hose to the barb on the manifold though. There would be nothing wrong with it, but if you ever had to replace that hose again in the future, it would make it just that much more difficult.

Hi Charger,

OK, I used the barb fittings for extending the hose, but it still leaks at the PVC manifold connection. I see there are no barbs on the manifold connection. I guess the next step is using cement. Will the cement work with plain vinyl tubing? any special cement? Can I build up the pvc a little with several coats of cement? Thanks again.
