300DS drains

[Concord]

Hello I have a 2019 Concord and I need some help. Have been in rv for 2 months and today while shower is on there is water pouring out of one of two drain tubes directly above exhaust pipe. This is behind passenger side rear tires. These are not low point drains and only happens when the shower is on. All tanks are drained. Not sure how to address this problem.
TIA

It would help if people knew exactly what year make and model of rig you have, and then you should post it under THAT forum for other owners to see that may have the same brand.

The OP apparently has a Coachman Concord 300DS.

I have a 2018 Concord DS, but am away from the unit for about a month and can't get first hand look at my unit. First thing I would check is pulling the inspection panel under the shower in the hall and see what you can see under the shower pan. You may have a leak where the water is following lines down. I know grey tank is there in that location under shower as well.

There is also the inspection panel on the bedroom wall behind the shower control knobs that is in the hollow wall. Check those connections and you can flashlight see down to the floor as well.

A picture of those drain tubes might help. Are they the same color and are they low point drains?
