  • Can One Valterra W01-1573 Self-Regulating Cable Be Used on Water Supply Line and Holding Tank
    You could certainly install the # W01-1573 heating cable in the manner you described. It would do a great job on the supply line, but how effective it would be on the tank will depend on the tank's capacity and size. Unfortunately, Valterra couldn't provide a 'rule of thumb' on the size of tank this particular set up would be best with. I'd run the line straight against the supply line, and run the element serpentine fashion on the underside of the tank, keeping the loops about a foot...

  • Pipes That Valterra Self Regulating Heat Element can Work With
    The Valterra Self Regulating Heat Element would be able to work with the flexible plastic as well as PVC pipes so long as they are no more than 3" in diameter. This unit comes in three different lengths, 15' # W01-1572, 25' # W01-1573 and 50' # W01-1574. I've added links to a couple video reviews of these products for you to take a look at.

  • A/C Powered Heating Element for RV Plumbing
    The Holding Tank Heater Pad for RVs part # 277-000164 operates off of D/C (direct current). It will need to be hardwired into your RV's wiring harness. For an A/C (alternating current) option, I recommend using the Valterra Self Regulating Heating Element part # W01-1574 as this will also work well to heat your motorhomes holding tanks, water supply lines, drain pipes, metal pipes up to 3" in diameter, and plastic pipes up to 3" in diameter.

  • Solution to Prevent Plumbing on Slide-In Camper From Freezing
    Heating pads such as the # 277-000164 are designed for 29 to 40 gallon tanks which are much larger than the tanks on your Lance 650 truck camper. My fear is that they could possibly get too hot and damage the tank. From what you describe, a solution such as a self-regulating heating cable such as the Valterra # W01-1573 for a 25 foot or # W01-1574 for a 50 foot length would be your best bet. The cables operate on 120V AC power, so you'll need an inverter like # DU89FR to power them. I've...

  • Where and How to Install Valterra 25-Foot Self Regulating Heating Element W01-1573

  • Can More than One Heating Pad be Used on a 100 Gallon Fresh Water Tank
    You could use more than one holding tank heater if you wanted to and there are different options available. Pad heater # 277-000164 is one option. There is also another model, # 277-000163, with different dimensions. We also have elbow heater pad # 277-000161 (for 3 inch pipe) and # 277-000162 (for 1-1/2 inch pipe).
