Rear Exterior Shower Connectors Leaking

[MikePapa]

While winter camping for a couple months in Colorado, my exterior rear shower connectors are freezing & leaking. I expect freezing weather every so often & am using all the techniques to prevent freezing pipes, but I can’t seem to prevent this shower from freezing which is causing the connectors to expand & leak. Last time I partially removed the underside & was able to hand tighten the connections on the back of shower once above freezing. Leaking again after another round of low temps & wish there was a valve to prevent water from going to the shower for these circumstances. I use a heated light under Rv to help prevent fresh tank freezing along with continuous running of furnace. Skirting is not allowed. Being so far on the rear of Rv, it’s hard to get heat there. Any ideas? Different connections or plumbing thread on connections or potential valve somewhere I don’t know about? 2020 Montana High Country 385BR

Mike,

Do you use the outside shower? If not, you might consider cutting and capping the line.

[MikePapa]

Thank you for the response. We do use it quite often, more so in the warmer seasons. So I don’t necessarily want to cut those off & cap.

Don't cap them then. Just install a shut off. Very quick and easy with a Sharkbite if you can get to the water lines.

When you partially removed the underside did you happen to take any pictures of what it looked like under it?

I ended up removing the hoses from the shower to the mainline and replace them with basic sink hoses from Home Depot. I wrapped them as well. Pics don’t show wrapped.

If you are on city water, turn it off and allow it to drain a bit. If on pump, turn it off at bedtime and drain a bit from any water tap.

[MikePapa]

Thank you. Definitely will do that. Good advice.

Can you do the suggested above?

[MikePapa]

Sure can. Great idea. Thank you.
