Last fall when I was winterizing and was running antifreeze through the shower we discovered a leak in the shower drain. Antifreeze started running out from under the shower. We never noticed the leak while someone was actually in the shower showering.

So today in an effort to access the drain I removed the exterior shower. And of course had to disconnect the lines to it. So I drained the antifreeze out of those lines.

So far I haven't done anything else yet. Waiting for my wife to come home to pour more antifreeze down the shower drain while I watch the drain from outside hoping to see where the leak is. I still don't have real good access, I can see it but can't really fit my arm to it, maybe my wife's smaller arms will reach.

Anyway do I need to get antifreeze back into the fresh water lines that I drained to remove the exterior shower?

We are having a pretty mild spring and only supposed to get down to the low 30s for a few days, but I'm sure we'll get another hard freeze before spring is over.

 

You don't need the lines to be full of anti-freeze, you just need them to NOT have fresh water in them. So if they previously held anti-freeze, and that has drained out, you don't need to worry about it.

Lots of folks winterize by blowing the water out with compressed air, so they dont' use anti-freeze at all, and have no issues.

 

Can you post what model & year your RV is? Thanks. Most include that info in their signature line.

 

While you are at it, put your location in your profile, and your truck info in the signature line as well.

 

When you anti-freeze for the winter you need to anti-freeze your drains also. The traps hold water that can freeze & break drain pipes. On the newer trailers with pex water lines the pex doesn't break the plastic fittings do.

 

Do you have one of those little mirrors on an expandable rod. With a flash light, might help you see around corners.

 

Since they noticed the leak when someone was showering, I think the lines have water in them again, if I read the post correctly. Still can blow them out, but hard to do if some lines are disconnected.

 

So we did a little detective work, we poured antifreeze down the shower and could not get it to leak. Then I hooked the exterior shower back up and pumped some antifreeze through the lines without any of the faucets on. And sure enough here comes some antifreeze leaking out from under the shower.

There has not been any water in the lines since August.

The only line under there is the fresh water to the toilet.

It is the old grey pipe. So my plan is to snake some pex line through there and use the seatech connectors.

Does that sound reasonable?

 

sure that will work. Is your camper so old it is plumbed with butyl? Butyl is grey.
