🔍 Valterra 1/2" MPT x 1/2" MPT Check Valve (P23415LF) - Enhance Your SEO! Review

I think an anti-corrosion bar in the sewers would be essential if you plan on using them. The only difficulty with the project was that, like many RV modifications, the water heater is a little tricky to access. So if you don't have the patience…

If you own a Lance Truck caravan/trailer and want to replace the plastic inlet and outlet fittings on the hot water tank before (in my case after) they crack and break, buy this. It has a built-in check valve with an arrow showing the direction of flow. I used liquid pipe sealant (Permatex brand) for the side connections of the tank and simply hand tightened the existing PEX piping on the other sides. IMPORTANT NOTE: Be sure to check for leaks after filling the water heater and heater. . When…
