Emery has a photo album showing that repair.
I am on a phone and can't locate the link -- but a search should find it.

...I'll finish it up tomorrow and post the rest of the photos.
Also replaced the hot water controller and the hot water now doesn't boil in the tank.

So you will be camping in the driveway tomorrow night and heading to FL Saturday?
|
Actually we camped in the driveway last night. We spent the entire night. Didn't sleep that well but it was probably something that we'll get used to. With this delay, we're probably not going to make Florida until after Christmas. We'll probably go to a local state park for a few days. The problem is that there isn't anything to do around here. But we need to have a shake down so we can get ready for some of the spring rally's. We want to do Dothan and Bean Station for sure.

Kerry, I don't know why but "white" pipe is usually PVC and is used underground, "black" is ABS and is used above ground. If I was going to use "white" above fground I would want to make sure it would last.

It has to do with sunlight. Ultraviolet light degrades PVC plastic, and it will eventually fail in sunshine. It needs UV retarder in the mix to survive in light. This is why black Ty-raps<tm> should always be used outdoors. The white ones will fail in UV.
One of our manufacturers built some high intensity strobe lights using door switches which were made of PVC, their rationale being "The switches are in the cabinet, thus the sunshine won't affect them." It didn't either, but the strobe tube six inches away discharging 500,000 candelas 40 times a minute sure did. They hadda change all the switches, including the set of nine I had ranging up to somewhat over 900 feet in the air.

My experience is PVC is for potable water and ABS is for waste (although I have seen PVC used for waste as well). I don't believe it has anything to do with above or below ground. I have never seen ABS used for potable water. There is probably a reason based on the chemistry of the pipe. Both types will break down in sunlight.
When both types are connected to each other, you need to use the "PVC/CPVC/ABS" cement. If you use PVC cement on ABS (and vice versa) they don't bond.
If Kerry used the correct cement, and the pipes are not exposed to sunlight, his repair will outlast the GMC.
I can run the above past a professional pipefitter if anybody tells me I am spreading misinformation.

I saw Mike Hughes on another thread. Mike is a retired union pipe-fitter and could certainly answer this question. I will try to shed a little light on the subject. I am not a plumber, but a General Contractor.
ABS (black) has been used for waste lines for years, both underground and overhead. PVC has normally been used as water supply lines, mostly for main lines. Recently, (In the last 10 - 15 years) more PVC drain fittings have become available. That is what Kerry used in his drains. PVC is more acid resistant than ABS. I believe both need to be protected from long term exposure to UV, but especially PVC.
My coach has a chase mounted to the bottom of the frame, for storage of the macerator hose. It runs under the rear sway bars (part of the brake reaction arm system) and is very close to the road. The material is electrical PVC conduit (gray). I live in one of the most extreme climates, in terms of heat, in the US (Southern Arizona) and it has not been affected by road heat at all.
