The Big Picture
Where this fits in your home's plumbing
Fresh water comes in under pressure, hot water gets made and piped to fixtures, and everything drains downhill to the sewer. Here's the whole loop — and where this service fits.
- Water main, shutoff & treatment Where city water enters — the shutoff, pressure regulator, and any filtration.
- Water heater Tank or heat-pump — it feeds every hot line in the house.
- Tankless water heater You're here Wall-hung, endless hot water heated on demand instead of stored.
- Kitchen plumbing Sink, faucet, disposal, dishwasher, and ice-maker lines.
- Bathroom plumbing Toilets, tubs, showers, and the supply and drain runs behind them.
- Drain lines & stack Every fixture drains into the stack — where clogs build up first.
- Sewer lateral The buried line from your house to the city main — roots and age live here.
- Sump pump Keeps groundwater out of the basement through wet Puget Sound winters.
- Gas lines Fuel supply to the furnace, water heater, range, and fireplace — leak-tested.

What moves the number
Tank vs. tankless vs. heat-pump
Tankless and heat-pump units cost more up front but last longer and cut energy bills. A like-for-like tank swap is the most affordable option.
Fuel type
Gas, electric, and heat-pump units have different equipment, venting, and electrical requirements that change the total.
Code upgrades
Washington code may require an expansion tank, new venting, a gas-line adjustment, a drain pan, or an electrical circuit — especially when changing fuel or type.
Location & access
A tight crawlspace, attic, or upstairs closet takes longer than a garage install and can affect labor.
