Where Is The Fresh Water Holding Tank Drain Plug On My RV?

by Betty

I have a 1987 Itasca Class C and I just can't remember where the drain valve is for the fresh water tank.

It has twin beds and the tank and pump is under one of them and I thought that was where the shut off valve was but I can't find it..need to close it to put water in.

It was opened when the service man winterized it...I've closed it before but I just don't remember.

ANSWER: Greetings Betty thanks for submitting your question on our Ask An RV Question Page.

I hate when that happens :-) I cannot tell you exactly where the drain plug or petcock for your fresh water holding tank is on your model RV. Normally the drain plug is on the tank itself at or near its low point.

There is a sure way of finding its location and also finding out if the drain is opened or closed. You should try to fill up your fresh water tank very slowly and the water will start to come out of the tank and then you will know for sure where it is located.

I hope that this helps you.
