Then there is the Puget Sound winter. The lagoon and bay keep the air damp and the wind funnels through the gap toward Wauna. Hard freezes in December 2022 and January 2024 froze crawlspace lines on waterfront cabins and exposed pump houses. Winter rains raise the water table under the shoreline lots within days. At about 20 minutes from Port Orchard down Highway 16, the closest Pierce County stop we have from Port Orchard, Purdy is a regular line on our schedule, not a special trip.
Why tankless water heater installation is a little different in Purdy
Winter water comes into Purdy homes cold, and that limits how many gallons per minute a tankless unit can bring to shower temperature. We size for the coldest month so two fixtures at once still work in January.
Start with the homes. Older waterfront cabins from the 1940s through the 70s along Burley Lagoon and Henderson Bay, 1980s and 90s homes on the uplands, and newer construction spilling north from Gig Harbor North. The waterfront homes are the ones with galvanized supply lines, cast iron under the floor and septic pump chambers; the newer ones bring PEX and tankless heaters.
Local conditions that affect tankless water heater installation in Purdy
In Purdy specifically, one issue comes up more than most: Galvanized supply lines in 1950s and 60s cabins choking flow
Propane is common on Purdy acreage and cabins, and Rinnai propane models work well there. We set up the regulator, drip leg and venting for propane and size the unit for the household.
Ask a Purdy homeowner what goes wrong with plumbing here and you will usually hear a version of this: Septic effluent pumps and alarms on low shoreline lots around Burley Lagoon
Purdy homes with a pressure reducing valve still need a small expansion tank on a tankless system, and homes on wells need a sediment filter ahead of the unit. Both are included where your house calls for them.

Tankless Water Heater Installation questions from Purdy
How long does a tankless conversion take in Purdy?
Most are done in a day with hot water back by evening. Adding a gas line to a new location or running a long vent can push it to two days, and we tell you up front.
Do you service tankless heaters in Purdy after installing them?
Yes. We descale and service tankless units across Pierce County, and most customers put the new unit on a maintenance interval matched to their water.
Will a tankless heater work on well water in Purdy?
With a sediment filter and a regular descaling schedule, yes. On very hard or iron-heavy wells we discuss filtration first and will say if a tank is the better fit.
Do you pull the permit for a tankless installation in Purdy?
Yes, for both the plumbing and the gas line, and we schedule the inspection.
Will my existing gas line work for a tankless heater?
Often not without upsizing. A tankless burner draws several times the gas of a tank heater, and lines sized for a tank and a stove starve it. We calculate the load and include any upsizing in the quote.
