watertank breather

If you have an underslung watertank on your camper trailer & have trouble filling it, odds are you do not have a breather hose for air to escape. This shows you how to install one.

Remove the blank plug in the top of the tank & drill a hole into the tank at the base of the threaded hole.

Install a 90 degree breather elbow. You may have to hold the end of the hose in some boiling water to get it onto the barbed end of the breather elbow.

Attach a suitable length of 12mm drinking grade water hose with a hose clamp. This type of hose does not taint your drinking water.

Reinstall watertank & connect end of hose to breather on filler with a hose clamp. Most good water fillers have a breather outlet built into them.

If you have not got a breather outlet on the filler, try to  place the end of the breather hose as high as you can get it & secure with hose clips & cable ties. If you have it down low you could easily get your drinking water contaminated crossing a creek or just full of dust.

You shouldn't have any trouble now filling you tank with a hose at full pressure.
