Sanitizer flush line leaking

[eprver]

Original owner 2006 Bighorn 3055RL

While flushing black tank water with sanitizer flush system, it started leaking on entry way floor from under wall between stool room an entry way. Removal of fire extinguisher panel panel showed clean water (thank goodness) running down a plastic line on right side of wall separating entry way and stool room. Can't reach up high enough to feel leak. It looks like I need to remove entry way mirror door and closet to get to leak. Not an easy adventure.😟 Any previous experiences with problem or repair idea before I get out the jig saw? Thank you

HI eprver,

Welcome to the Heartland Owners Forum and to the family. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.

Sounds like it might be the back flow preventer. Most are located behind the shower. Look in the shower below the handles and you should have about a 6" round cover that will unscrew. Remove this and see if you can locate two pex lines hooked to a fitting and the lines are not hooked to the shower, just positioned behind the shower wall. Let us know what you find.

Be sure and check out our Heartland Owners Club. Join us at a rally when you can and meet lots of the great folks here and make friends for a lifetime.

Enjoy the forum.

EPRVR and Jim:
The early build Bighorns had the black tank flusher plastic atmospheric breaker (check) valve mounted high up on the interior wall behind the toilet. Voice of experience here. It is mounted higher than the sink in the bathroom to conform to a code requirement, which makes no sense to me since the sink is on one of the grey tanks, not on the black tank with the flusher. My flood washed over my power converter/charger mounted on the storage bay utilities crawlspace floor directly under the downward tubing from the breaker valve. My converter/charger was ruined to the tune of $250. This happened at the start of an extended road trip. I chose not to tear off the wall facing behind the toilet (which in retrospect would have been much easier than the sawing a hole up through the flooring route I chose).

Here is a link to one of my old threads on the subject: https://heartlandowners.org/showthread.php/33612-Black-Tank-Washer-Breaker-Valve?

Do not cut the wall, just bypass the valve by cutting the line going to it. You will find the lines behind the basement walls. Add a check valve to the water inlet, for the flush system, behind the inlet. I and many people have done this. You can get a check valve at any RV parts store. The anti-siphon valve is there by RV code but is not a necessity to be there.

Thanks for the feedback. I think I have a picture of the problem. Currently wintering in Arizona. Will flush black tank the old fashioned way till we get home in a couple months and fix problem..It appears we have 2 lines running up wall behind stool room and a antisiphon/check valve will do the trick but think I want to be at my shop with all necessary tools. Also looks critical to have ALL power off while making repair. Since my bride likes NOT to be without power too long, I will wait to get home. Most repairs seem to always take longer and cost more than planned😁....Thanks again for everyone s inputs..

When the plastic UDC fitting for the flusher fell apart, I used a brass city water inlet with check valve to replace it. When the anti-siphon valve failed, I pulled the lines out of the wall, cut the valve out, and put a Sharkbite check valve in place of the cheap plastic thing and secured the line to the floor above the black tank.
