Hanger Strap for Gray Water Pipe

[gfarmcafe]

Every since we got our 2011 Wind River, I've been concerned with how much play the gray water pipe has where it attaches to the frame near the dump cap. There's just a thin strap that holds the pipe up and is very flexible. I'm always afraid of something separating when pulling or pushing on the dump valve.
Question is - Is there a reason for this such as absorbing bumps and vibration? I would like to attach a stiffer, metal 1" steel strap to the frame.

Also, I've noticed the PVC piping was made in Canada, so it was either built using those parts at the factory, or spent part of its' life with you fine folks up north.

If the strap is not holding the weight of the pipe you might want to snug it up or if that can't be done change it. Its not holding much weight so it doesn't have to be very strong.

Since the drain pipe is not made in the the USA it should be changed to prevent a blow out. Some would call them canuck bombs. They are not dangerous, just a nasty mess when it does blow. Cheers.

But it will apologise if it does explode.

No matter how good Canucker plastic might be ... if it is allowed to flex too much during travel, it's just a matter of time before something starts to crack. The right road harmonics can cause some serious flexing motion. Likely it'll leak for awhile before it completely gives way. However I find flex induced cracks happen in the worst spots for repairs so preventing them is certainly something to consider

Steady pluming sturdy, while leaving some flex in the assembly and it should last the life of the RV. Too loose or rigid is a gamble on "when" a problem occurs. Though I'd rather error a little on the rigid side for RV pluming. Maybe think of automotive exhaust system hangers when judging for how much flex. Longer runs steady best with multiple contact spots.

Sorry, I missed noting that.

Since yours is a 2011 as well here's how ORV did our Creek Side. The straps are taught and the pipes are held very rigid with no movement at all. Ours drains are ABS, not PVC.

I don't know if the photo helps or not but here's a pic how ours was done.

Your hangers are the same as ours, but much more flexible. Our black water outlet is located ahead of the axles and the gray is behind towards the rear of the slide. I think part of the problem may be due to the long run the gray water plumbing has to take to the rear valve.

[60sumtin]

Yeah both our tank drains have quite a short run. Both are behind the axles. A couple of extra galvanized hanger straps should help.

My rear grey water pipe hanger broke, and I replaced it with metal plumbers tape.

Neither the original hanger nor my fix are very rigid. They just keep the pipe from extreme deflections.

A more rigid hanger, would be better. Haven't figured how best to jig one up though.

We've put a lot of miles on some pretty bad roads with it as it is, and so far so good. (knock on wood).

The issue here is that the hanger has to be sturdy enough to support the pipes, yet not allow too much flexing.

Flexing, or making the strap too tight is inviting problems where they attach to the tanks in my opinion.

Other than checking mine, I've left well enough alone in this area. I ran over a road alligator (semi tire carcus) that was thrown in front of me by a car on the return trip Friday.....lucky it hit the front storage door, and deflected away from the trailer bottom. It would have taken the pipes out for sure.
Did some damage to the cheap diamond plate though.

[60sumtin]

Considering the trailer is a 2011, and the drains have not cracked by now, I don't think there's anything to be concerned about. At the very least there should be support near the valves. IMHO a bit of flexing is not an issue. ABS is pretty robust. ABS will expand, contract, and bend on its own just through temperature changes and will do so even more the longer the length of run so don't secure them too rigid.

Although I do not own an orv trailer yet, that’s what I have also done to other tt , plumbers tape..
