Shower backup

Hello, my shower in my heartland 2015 Bighorn keeps backing up or maybe it won't drain. My husband has removed the vent cap and blown out the lines and has replaced the p trap. It still won't drain properly. It's not an issue with the grey tank. The bathroom sink and the kitchen sink drain fine. Any ideas?

Here is a link to just one of the RV tank cleaning services out there. Most all of these services have the specialized knowledge and special equipment (like video fiber optic inspection tools) about RV waste water systems. This vendor is nationwide with local franchised servicers, and they come to your rig. Check out other possible companies with an "RV Tank Cleaning Service" web search.



Good luck and God Bless!

Had issue slow draining shower had to flip up that drain cover in shower and clean out the drain itself

We had this issue in our '23 Milestone bathroom sink.

When my husband removed the gooseneck, it was discovered that it was FULL of construction material. As in all the little end pieces from the walls and frames. Cleaned that all out and haven't had an issue since (obviously.)
