My wife and I bought a mobile home that was assembled with Qest water pipes. (This brand of plastic pipes have proved to be very unreliable to consumers all over.) In the two years that we’ve been here, I’ve made about 4 stopgap repairs. This was made more difficult because in addition to the poor quality piping, the installers put in no cut-off valves to the individual fixtures. I had to crawl under the house and turn off the water main every time I worked on a pinhole leak in the bathroom.
So, we’ve decided to replace the piping in the house. We’ve heard quotes from neighbors for several thousands of dollars, using copper piping and professional installers. Then my wife got the idea: why don’t we (i.e., I) do it myself using CPVC? It’s cheaper, and I’ve proved myself somewhat in plumbing repairs.
Well then, that brings up the OP. I plan on doing this myself and perhaps with a friend. Can I do this without having to bail and call in a professional?
Details: all the piping is under the house, in a literal crawlspace (30 " high). I just need to remove some fiberglass insulation to get at the piping runs. (Some of it’s already ruined from water leaks.) I’ve got 2 full baths, a kitchen sink, a dishwasher, an ice maker, a clothes washer, and a water heater to get connected. And I’ve got 4 full weekends and 6 hours on the following 3 Wednesdays.
