Water heaters for larger Federal Way households
Federal Way has a lot of busy family households. More people means more showers, laundry and dishwasher loads, and a 40 gallon tank that was fine for a couple often runs cold for a family of five. When we replace a water heater here, we ask how the household actually uses hot water before recommending a size.
| Option | Where it fits |
|---|---|
| Heat pump water heater | Garages and basements with room around the unit; lowest running cost on electricity |
| Gas tank | Homes with PSE gas and an existing vent |
| Tankless gas | Big households that want hot water without running out |
| Electric tank | Tight closets in townhomes and apartments |
PSE electric customers can get $1,000 back on a qualifying heat pump water heater, or $1,100 with Efficiency Boost, as of September 2026 (PSE heat pump water heater rebate). We are a PSE Trade Ally for water heaters and file the rebate for you. Tanks we install are strapped against earthquakes, as the plumbing code requires.
Lakehaven or a plumber: who fixes what
Water and sewer in Federal Way come from Lakehaven Water and Sewer District (City of Federal Way, Who Do I Contact). A simple rule of thumb: problems on the district’s mains and at the meter belong to Lakehaven, while pipes, drains and fixtures on your side belong to you and your plumber. If water is running where it should not and you cannot tell which side it is on, shut off your main valve and call; we will help you sort it out.
A sudden jump on your water bill usually points to a running toilet, a dripping fixture or a hidden leak in the supply line between the meter and the house. We test fixtures first, then trace the line.
Common plumbing calls in Federal Way
- Kitchen and laundry drains slowed by grease and lint, especially in busy households.
- Water heaters at the end of their life, leaking at the base or tripping the relief valve.
- Running and rocking toilets that need new parts, a wax ring or a new flange.
- Leaks under sinks from worn supply lines and shutoff valves.
- Outdoor faucets cracked by a hard freeze.
- Low pressure from a failing pressure regulator or old pipe.
Older pipe in homes built before 1990
Many Federal Way homes are older ramblers and split-levels. Homes from the 1960s and 1970s may still have galvanized steel supply lines that rust from the inside and slowly lose pressure. Some homes from the late 1970s through the early 1990s were plumbed with polybutylene, a gray plastic pipe known for failing at the fittings. If your home has either, we can replace the worst sections or repipe the house with PEX or copper and give you a written price for each option.
Rental properties in Federal Way
Federal Way has a large share of rental homes. If you own or manage a rental, tell us who approves the price and who will let us in. We report what we find to the person paying, and we do not start extra work without approval. For turnovers, we can often replace a water heater, fix running toilets and clear slow drains in one visit.
Fixtures and remodel plumbing
Updating a kitchen or bath? We replace faucets, sinks, vanities, toilets and shower valves, add laundry and utility sinks, and rough in new supply and drain lines when a remodel moves fixtures. For bigger projects, we price the plumbing in writing so you can plan the rest of the work around it.
Winter freezes and your pipes
Federal Way winters are mild most years, but an occasional hard freeze still splits outdoor faucets and pipes in crawlspaces and unheated garages. Before a cold snap, disconnect garden hoses, cover outdoor faucets and keep the garage door closed. If a pipe does burst, shut off the main valve and call us.
Plumbing permits in Federal Way
The City of Federal Way issues plumbing and mechanical permits and accepts residential applications online through MyBuildingPermit (City of Federal Way, Permit Center). Water heater replacements and repipes often need a permit. We check what your job requires, pull the permit and schedule the inspection.
When to call right away
- Water spreading from a pipe, tank or fixture you cannot shut off.
- Sewage backing up into a tub, shower or floor drain.
- The smell of gas near a gas water heater: leave the house and call PSE first.
- No hot water in a home with young children or older adults.
