Propane Line to a Pool Heater in Maple Valley, WA

Open trench across a Maple Valley yard with a yellow underground gas line running to a buried propane tank, excavator in the background — Underground propane tank, Maple Valley

We teamed up with local propane and pool contractors for this large build. To be clear we do not set propane tanks, only run the gas lines to and from them.

This large log cabin will be a back yard resort after this project. An infinity pool, with all of its equipment hidden in a below ground bunker. The pool company used an excavator to dig the trench and final site for the underground tank, plenty of room to work and run our lines in.

Our scope

The run was approx. 60′ from the tank. You may notice the line looks small for the equipment. This is an advantage propane has over natural gas running at higher pressures and carrying more BTUs per volume. The best design choice of the project was hiding the necessary equipment in an underground bunker. No eye sores to take away from the beautiful landscape
