Grey "quest" piping??
So I hooked up the water on my new (to me) 1997 Gulfstream and found leaks at the kitchen faucet. I promtly shut the water back off and am assuming there are more leaks. In your experience, would you ...

Quest was discontinued in 1995. It sounds like they were still using what they had in inventory on your trailer. Although PB pipe failures do occur, the primary leak problems are the acetal (plastic) fittings. If copper fittings & crimp rings have been used (properly installed) there is little concern. When cutting and modifying Quest piping, simply use Pex with brass fittings, onward from the point of interconnect. BUT, be sure to use the Quest X Pex conversion couplings. Although similar in appearance, there is a slight variation in insert size/configuration. There are several types of crimps, but if you are using copper rings, remember that copper color (natural) rings are on the Quest side and black rings are on the Pex side. Hope this helps.
