Low point drains

We have a 1994 Classic limited 34'. I have spent the better part of the day looking for low point drain valves. The manual says there are three of them...two under the fake floor under the microwave, and one on the street side near the rear bed. Their is a written note in the manual (PO?) that says there is just one under the curb side shirt closet(near the head of the rear queen bed). I cannot find ANY low point drain valves on this trailer!! Any help would be appreciated. John

May be Very Difficult to Access

We don't have a 34' but ours are very difficults to find. In addition, they don't look like the picture shown in our manual.

Assuming they are located where the manual (an maybe where the PO noted) be sure to look under/below any wiring, ducting, other hoses, etc. I can just barely get my hand into the cubby, under the wires, under the duct before I finally get just my finger tips on the valve. It's an ordeal to say the least. Now that I've done it a few times it's not nearly as difficult as the first time. I bet I spent the better part of half day searching for them the first time. They really are the low point in the plumbing system.

The best way to local then would be to get under the trailer at about the noted locations. Once you find the ends of the drains go inside and look. They are often below the floor line, below a TEE in the pipe, and covered with the rug. There should be a cut in the rug to see through and get your hand to the valve.

They are often very hard to open because they require a 1/4 turn as you pull out on the handle.

If you plow out the water lines with compressed air before adding any anti freeze there is no reason to open the valve when winterizing, The risk of breaking one is not worth the effert.

Thank you for your response. Maybe i will just not worry about it and try to blow the lines with air. Thanks again. John

Air is a great way to winterize but you still need to open the drains or they could split as the lines going to them can be lower than the other lines.

The valves are a small "tee" handles about 1" long and 1/4" wide. They are made of the same grey plastic as the rest of the plumbing and they are often down below other lines so you really have to look for them.

They need about 5 turns to open or close. As well the thread is stripped at each end so it will turn forever. You need to pull up slightly as you turn to open it.
