How Our hot water Crossover Circulation Works

Crossover Valve is for Faster Hot Water

We installed our advanced TGP Crossover Valve under the sink, which takes the longest to get hot water. This location allows the pump to move hot water to all the sinks and showers. The TGP Crossover Valve works with the temperature of the water. It shuts off when the hot water is 104 degrees and opens back up 95 degrees.   

Filtered Water for Your Home

Our Custom/3M Filtration Only Requires One Cartridge Change Per Year...

Our Custom/3M water filtration system will eliminate hard water and toxic soup, leaving you with clean, drinkable hot water and increasing system life to 20-years.

Here are just some of the impurities that will be eliminated;


  • 90% microplastics
  • Most calcium carbonate  
  • Some bacteria
  • Anthrax
  • Some molds
  • Paint chemicals
  • Red blood cells
  • Asbestos
  • Fertilizer 
  • Insecticides 
  • Chlorine
  • Iron
  • Chlorine
  • Sulfur

Hot Water Tanks are BAD

One 50-gallon tank water heater can collect 8 lbs. of toxic sediment
