Tankless Water Heater Installation in Manchester, WA

Tankless conversions in Manchester are a regular job for Washington Plumbing & Drain, and each one starts with the questions that decide whether it will work: what fuel serves the house, whether the gas line can feed a large burner, and what the water will do to a heat exchanger. We install Rinnai units across Kitsap County with the gas, venting and isolation valves done properly.

Where the drains end up matters just as much. Kitsap County Sewer Utility operates the Manchester sewer system and treatment plant, covering the village, Colchester and the denser blocks near the water. The plateau above Mile Hill and the larger lots toward Woods Road are largely on septic. Manchester is about 15 minutes east of Port Orchard along Mile Hill Drive and Beach Drive, which puts it comfortably inside the territory we cover every week.

Why tankless water heater installation is a little different in Manchester

Many older Manchester gas lines were sized for a tank heater and a stove. A tankless burner needs much more, and we calculate the whole-house gas load and upsize the line as part of the installation rather than letting the unit starve.

Weather does the rest. Exposed to the east across Puget Sound, so winter storms hit the Beach Drive waterfront head on and send spray over the seawalls. King tides stack with rain to push water into the lowest drains near the harbor. The December 2022 and January 2024 freezes split hose bibs and crawlspace lines in the older cottages that were never insulated underneath.

Local conditions that affect tankless water heater installation in Manchester

Here is a Manchester detail that changes how we approach the job: Frozen pipes under cottages with open or poorly insulated crawlspaces

Manchester 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.

The pattern we see most in Manchester is this: Cast iron drains and galvanized supply in the Beach Drive and Yukon Harbor cottages

Winter water comes into Manchester 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.

Tankless Water Heater Installation questions from Manchester

Do you service tankless heaters in Manchester after installing them?

Yes. We descale and service tankless units across Kitsap 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 Manchester?

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 Manchester?

Yes, for both the plumbing and the gas line, and we schedule the inspection.

Can you replace my old tankless unit in Manchester with a Rinnai?

Yes. With the gas and vent already in place it is usually a short job, and we correct anything the original installation was missing, such as isolation valves or undersized gas.

Can I convert from an electric tank to a gas tankless?

Yes, if the house has gas or propane service or you are adding it. We run the gas line, the vent and the water connections. If there is no gas service at all, the utility or a propane supplier has to set that up first.

★★★★★
Greg is awesome! He came out to service our thankless water heater (which hadn't been serviced in 11 years) and did a great job. He really put in a lot of effort to minimize any mess that it involved and was very personable during the job. His communication is also very clear.

Gregory did fantastic work descaling my tankless water heater, was in and out within an hour. They texted me when he was on his way and gave me an ETA which was MUCH appreciated. Kind, courteous and professional. I will be using them for my future plumbing needs.
