Plumbing replacement
I have a 20 year old park trailer - 35'x14'.
Every spring I got couple pipe leaks. All plumbing is original was done in PVC tubing. This spring I got three big cracks in the tubing and I am sick and tired of it. One was in underbelly and was ugly. I am thinking to replace the whole system with PEX. Any recommendations? I have never done it before. Where can I get a schematic for 1984 Park Avenue mobil home? I got an estimate from a local guy for $1500. I want to do it myself.Where do I start? Thank you |

Re: Plumbing replacement
If the cracks are due to stress from freezing, I would try to seal everything up and insulate it good. Start with covering all the pipes with the foam sleeves made for that. Your best bet might be to improve any skirting you have, making it air tight, and then covering the inside with fiberglass insulation. In addition to preserving your plumbing, that would give you a warmer floor and lower heating bills.
I am not sure the PEX would stand freezing much better than the PVC would, and you may have to go through a learning process in order to make good tight joints, as well as buying expensive tools you won't have much use for afterwards. Part of the $1,500 the guy quoted was for knowing how to work with the PEX and having the tools. |

Plumbing replacement
In my area of Florida we have many mobile home factorys. Back in the early 70's I worked as a plumber in some of them. We piped our trailers in soft type"L" copper and had no complaints. I would insulate my pipes in the foam sleeves, (Armoflex) as Labman suggested, against freezing. Since your going to have to open up the sub-floor to get at the pipes to replace them you won't need a set of plans. Just follow the pipes and replace with the same connections. I have had no experience with pex in cold climates so I can't help you there. Kudos for taking on a tough job, Tom

Yes, PEX will handle freezing
According to the manufactuer, PEX will expand to handle freezing water (see link)
http://www.durapex.com/Dura-Pex.asp Of course, you _fittings_ probably won't... But exposed portions of straight PEX should freeze/thaw fine according to the manufacturer.. :) |
