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

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 the water tank is heated, additional pressure is created in it. I found I had to re-tighten the connectors to stop the slow drip after testing. Real cheap plastic fittings tend to snap the threads as they move due to the up and down movement of the water pipes. They will never have this problem and are now factory installed on the latest Lance models. Worth the investment.
