Hey all,

I have been running through my checklist getting ready for my trip to Texas at the end on next month. Today was water checking and it was not a good check. I didn't check the water workings before buying and wouldn't you know it that is where a bunch of issues are showing. First and most important is the 90 degree fill elbow that goes into the tank is leaking. I am assuming this just needs to be epoxied but wanted to get opinions from the experts. Second is a two leaks between the bathroom sink and the kitchen sink. The first was both pipes cracked directly under the sink so those should be no problem to fix. The other is in the coach walls between the two sinks. My question there is how much dismantling is required to access them. Also, is pex recommended in our coaches?

Thanks,

Chris

Chris,

The fresh water tank is made from Polyethylene and is essentially impossible to glue. Now being stubborn I was able to make a reasonable temporary fix by plastic welding and using some of the epoxies on the market to build up my repair. A new tank is still in my future. You can try this http://www.tapplastics.com/product/repair_products/plastic_adhesives/tap_poly_weld_adhesive/435 which claims to work. I bought it but never got around to using it. Good Luck!

Chris,
JB water weld fixed the leaks in my water tank. Available many places. Got mine at Autozone.

PEX is ideal for the coach. Search the forum for more comments on PEX. I'll use it when my copper fails me.

There is at least 2 page of photo albums that show PEX installation in the GMC motorhome. In the search area type in pex.

Just went though one of the many. Is it really needed to take out the
fridge and open the divider to the bathroom module to replace the pipe
coming from the bathroom to the kitchen?
