Miramar shower leak
Our Miramar 35.3 is back at the dealer for the 3rd time for a shower leak. A few minutes after taking a shower, water will start weeping out from underneath the from corner of the shower. Sometimes you don't notice it but if you take a paper towel and push on the panel that is on the front of the shower, water will weep out onto the paper towel. In testing for the leak before I dropped it off, I filled a 5 gallon bucket about half way with water (from an outside water source) and poured water down the shower drain. I figured this would rule out water leaking from the the hot/cold values and also rule out water splashing onto the door frame or other areas of the shower. In doing this the first time, I didn't see a leak (or I didn't wait long enough). My second test I filled the bucket half way again but this time I stood in the shower when I poured the water down the drain. So now I have pressure on the shower floor from me standing in the shower. About 5 minutes later I checked with my paper towel trick and no water. I came back about 15 minutes later and sure enough, water weeped onto the paper town when I pushed on the front panel. It's like the water is dripping from underneath the shower pan and eventually pooling up against that panel piece in the front of the shower. I noticed that the trim near the floor coming into the bathroom (which is next to the shower) was coming loose due to the water.
Camping world called yesterday afternoon and said they had calked the shower door frame and some other areas (which was done the first two times I took the motorhome in for the leak). I told them that this wouldn't fix the leak since I know the leak is coming from underneath the shower. It's got to be coming from the shower drain or the plumbing underneath the shower. My service tech said there should be some type of access panel to get underneath the shower for the plumbing. I'm not sure how since the grey water tank seems to be right underneath the shower. If I go outside and open up the compartment under where the shower is, there appears to be a tank. I believe there is a furnace vent that comes out the front of the shower near the floor so there is definitely room underneath the shower. I guess that front panel will need to be pulled off to get access underneath the shower pan.
For the Miramar owners, do you know how to access underneath the shower? My guess is when I get the motorhome back from the dealer it will not be fixed and I will have to eventually fix it myself. I dropped off the motorhome 2 days before my warranty expired and they have now had it 2 weeks so no more warranty.
