Installing an aftermarket RV tank heating pad is simple and fairly inexpensive. First, clean the outside of the holding tank, wiping away any dirt. Then wipe down the area where you’ll be applying the adhesive with isopropyl alcohol.
Once the surface is dry, line the heating pad up near the drain point, which is the lowest point of the holding tank. Then pull back the adhesive and slowly and tightly secure the heating pad to the holding tank. Ensure there are no air pockets without pulling or tearing the heating pad. Press firmly along the edges and center to make sure the RV tank heating pad is secure.
