Red Pex blew a hole just behind the outlet connection.

Is it my imagination or are the bulk of the busted hoses at the hot water heater outlet?

In my previous travel trailer I would always try to remember to turn th water off when leaving the unit unattended. I would also never leave the hot water heater on all of the time. I found that it would only take about 15 minutes to get hot water for a shower. Also would open the hot tap after hot water heater had been on for about 5-10 minutes and let out some excess pressure that would build up.

I know it is frustrating to have to do this on a unit so expensive. My previous travel trailer was cheap compared to these units. But until a change is made it probably ain’t a bad idea to take these preventative measures and HOPEFULLY they will help.

I noticed that the hot water is extremely hot, maybe the temperature being too high causes issues, it there any way to lower the temperature?

Following this "always shut the water off when you leave the trailer" logic . . . that is a good plan, if you always remember to walk around back and do this. We try to, but sometimes we forget. Part of my plumbing redesign and rebuild is to incorporate a solenoid operated ball valve at the water inlet connection. This is wired to the hot water heater switch. So, as long as I can remember to shut off the electric water heater switch at the main panel when we leave, the water will be shut off too.

WRT the temperature of the water . . . the standard water heater thermostat is 140F (I think) which is pretty normal. The problem is the hose, not the water temperature . . . no one has ever reported a Pex tubing failure, which is what all the plumbing should be (in my opinion). Except for Aridon's recent situation, these other hose failures are on trailers that have been in service for 4 years.

There are two hose failures mixed into this discussion. One is the drip leak at a hose to Pex fitting that has been disturbed. The second is a burst hose which is much more serious but also much less frequent. But . . . the oldest GDRV products are only 4 or 5 years old and the two examples so far are on these early production units . . .

Rob - do you think the change in the color of the flex piping is related to the quality of it. I've got the white flex pipe and I'm not showing any type of bulging in my 2014 Solitude. I'm fixing a leak in the black tank flush line where the flex joins the pex and while I'm at it, I think I'll replace the flex with pex wherever I can.

Hi Patrick - That is a possibility. I have seen pictures of the earliest builds that have white hose rather than the red/blue/black. It is certainly possible that this is a better product or perhaps fits the Pex fittings better. The only burst hoses documented so far are red water heater exit hoses on 2014/2015 Reflections. I have encountered the drip leaks from both red and blue hose to Pex fitting connections.

FYI, we are now all Pex and the problem with the hot water heater was a corroded “brown” wire with the resister.

That has to be a major contribution for peace of mind.

Were there any lines that disappeared and were hard to route the replacement?

Hey Mike - I have a picture just like that .

John - All the soft hose is in the “plumbing basement” behind the pass through wall, except the black hose to the black tank flush. The lines that leave this area and go to the kitchen island are already Pex. (At least on the 303 . . . the 337 is probably the same)
