Shower Incident - Awareness for All

We have a 2007 Monaco Knight motor home. Sometime during leaving or I expect returning from a Doctor's visit my wifeís razor which she uses to shave her legs; the unit is suction cupped to the shower wall above the faucets, fell from above the water faucets and hit the hot water faucet enough to open it to the Full-Open position. When we arrived my wife noticed the water running in the shower and ran to shut it off. We were extremely lucky! The water completely filled the gray water tank and was slightly leaking somewhere above the vicinity of the propane tank. We observed no evidence of water inside the coach. Does anyone know if the gray tank has an overflow valve? As I mentioned I did see water leaking at floor level near the propane tank, which is located next to the water bay. I checked beneath the vanity next to the shower and did not see any evidence of a water spill. I canít believe how lucky we were. I can only assume that the incident occurred on our way home and we arrived shortly after the gray tank had filled. In a normal situation once the gray water tank fills the shower base is the next area to fill then into the coach. I wanted to post this information to make everyone aware of what can occur if you have something fall from above the water faucets

Very interesting...it's really amazing how weird stuff happens. Your wife could probably throw that razor at that hot water handle for half the day and NOT turn the water on. Looks like the 'shower gods' were smiling on you just the same. Bob

I don't think a gray tank has an overflow; but in our motorhome, the pipes go into the gray tank through rubber collars. The collars don't seem to seal perfectly because one time I forgot to open the gray valve when we arrived at our stop, and DW ran several loads of wash and overflowed the gray tank. Unfortunately, in our motorhome, not only did the water back up into the shower (I caught it before any leaked out onto the floor), it leaked around the rubber collar and into the storage bays instead of around the propane tank.

My question would be was the shower pan full? If not then the connection between the shower drain and shower is not tight and the water ran out of the top of the tank and through the loose connection onto the ground.

Another example for why I turn the water off went I'm not going to be home. In the stick house the water heater pop off valve opened and ran for days. You don't even want to know about that water bill.

I now turn the water off when I leave either the stick and/or mh for any long period of time. And I don't leave the water pump on while traveling either.

I also turn the water off at the outside faucet. I also leave the Gray tank open as I have a flush system in the Black tank.I am really jumpy about leaking water as I left a faucet run in our stick house and did $14,000 damage to floors and walls. Marvh

Does anyone want to hear what happened to a friend of mine who left the shore water on after leaving his boat after the weekend?

I always turn off shore water when leaving the coach and do not travel with the water pump on.

My RV is old so this might not apply but our grey tank's vent is just a pipe slipped into a flange. No glue joint.

My grand daughter only turned off the water saver on the shower head but did not turn the faucets off after her shower. We all went to sleep and the shower head leaked very slowly through the night. I woke up in the middle of the night and the shower pan was full and just starting to overflow slowly onto the carpet. No overflow on the gray tank. I still ask myself why I just happened to wake up at that time and go and check the bathroom. You would think that if you make the fresh water tank at twice the capacity of the gray water tank that you would put an overflow on it.

First sentence, good. Second, I dunno. After our first campground sewer disconnect, I saw cockroaches a small child could ride living in and around the opening! YUCK! I'll never leave ANY of my dump valves open...well except to DUMP and then they will be CLOSED again within a New York second! I HATE cockroaches and ANYTHING that can live and thrive in such places and would prefer them to REMAIN where they live! Yikes! Bob

"I googled Can Cockroaches swim" It seems to be whom to believe. To come in from the gray tank they would have to negotiate one of three traps and make the proper turn at the proper tank pipe. So I don't worry too much. .Marvh

My gray and black tanks have vents but these come out at the roof level so if my water tanks did overflow it would be bad. Probably run down the steps when I opened the door. Yeah, what are the odds her razor was able to turn on the water. I usually turn off my pump when running and definitely when MH is not being used. Also turn off bat switches and gas valve at tank. Scared of a fire.

Thanks, Chiefdave for a thought provoking post.

After two separate experiences (a pin hole leak in a pressurized line and a pressure line that separated from the water pump) that were caught before serious damage occurred, we not only turn the water pump off when traveling, but cut off the water valve at the campsite when we're not going to be around the rig for any period of time.

In my working life, I was a utility billing manager for many years. Some of the horror stories I witnessed makes me very cautious about unattended properties (or rigs) with active water service.

I have always had the "can't happen to me" idea on this one. Time to reconsider, stick and MH. Thanks
