Last Sunday morning we had no water. My first thought was the water pump had frozen, it was 24 degrees during the night. Turned the heat on which also puts warm air into the lower storage area where the water tanks are located. After 20 minutes the water still had not started to run so I went outside to see what was still wrong.
We had no water with a small puddle under the coach. All the water in the take was gone, about 50 gallons. When I put in the expansion tank a couple of years ago I also put in a plastic drain value so I could drain more water out of the holding tank for winter storage. The value either failed or vibrated open. The small puddle was because most of the water had already evaporated.
The first thing I needed to do was get the valve out and fined something to block off the hose. I went through my tool box and found a plastic display fixture from a 1/2 in socket I bought a couple of years ago.
We got water at a place in Quartzsite that sells propane, water and sewer dumping. Water was $8.00 for 80 gallons.
