i think i have a problem i had water dripping out BY my fresh water tank drain. wasnt coming out the drain itself coming out the cardboard cover.no water was coming out the overflow drains. i opened the drain for my water tank water came out.now i havent used my water tank for years.my anderson valve it frozen on the city water.so now what is my problem why is water comeing out i guess my water tank some wear under there its leaking water some how.i dont think its the water tank i think its before the tank some how. now i turned the water off for a while turned it back on and it stoped dripping water. it stoped for a week or two.it started dripping again the water drain on the tank is still open no water comeing out of it.its dripping just like it did the first time.i turned the water off again for a while and when i turned it back on it stopped just like the first time. now i did take off the wall were the anderson valve is.ever thing looked good there.i looked down in side the bottom it was all dry in there.so i guess im going to have to take the bottom off to check it out dont realy want to but i guess i ll have to.im just wondering when is water getting there since the valve is frozen on city water.
