A while back our 5th wheel was at the shop for some repairs that included filling a void with some expanding foam insulation. If you’ve ever used foam insulation you know that it sticks to just about anything it touches. Ordinarily that’s not a problem and in fact it adds some structural strength to a repair.

Our repair required fixing a leak in one of the waterlines that ran through the void. I was concerned that if we foamed the void it would be a miserable job fixing a future leak should one develop.

The solution was simple and easy. Dave, the RV tech wrapped plastic bags around the waterlines and then squirted the foam inside the bags.

The result was the waterlines were immobilized and the void was filled with insulation but should we ever need to access the waterlines it’s a simple matter of breaking up the foam enough to remove the plastic bags.
