Water leaking right now? Shut the main valve, then book
If water is coming through a ceiling, under a sink or from a water heater, turn off your main water shut-off valve first. That stops the damage while you wait for a plumber.
- Find the main valve. In most Redmond homes it is where the water line enters the house: in the garage, a crawl space, a utility room or near the water heater. Turn it clockwise until it stops.
- Water heater leaking? Close the cold-water valve on top of the tank. For a gas tank, turn the gas control to "pilot" or "off". For an electric tank, switch off its breaker.
- Toilet overflowing? Close the small valve behind the toilet and stop flushing.
- Book the first visit. Book by phone or online. Our plumbers work Monday to Friday, 8 AM to 5 PM, with same-day service when possible. A request made in the evening or on a weekend is scheduled for the first available weekday appointment.
If the shut-off valve won't turn or won't hold, tell us when you book. Replacing a stuck main valve is a common part of the repair.

Redmond water and your service line
Redmond homes get most of their water from the Tolt River, and the pipe from the meter to your house is yours to maintain. According to the City of Redmond, about 60% of the city's drinking water comes from the Tolt River Watershed through its membership in the Cascade Water Alliance, and the rest comes from city wells. Homes east of the Sammamish River get a blend of the two; homes west of the river and on Novelty Hill get Tolt water only.
The City also says property owners are responsible for maintaining and repairing the service line from the meter to the home. So if the line leaks between the meter box and your house, or your water bill jumps while nothing is running, that repair is on your side. We repair and replace water lines on your side of the meter. Problems at the meter itself, or in the street, go to the City's water utility.
Water heaters in Redmond: repair, flush or replace
A water heater is usually worth repairing when a single part has failed and the tank is sound, and worth replacing when the tank itself leaks. Our plumbers work on tank and tankless water heaters, gas and electric.
- Repair: no hot water, lukewarm water, a tripped breaker, a pilot that won't stay lit or a leaking valve. The plumber finds the cause and quotes the repair on site.
- Flush: sediment builds up in a tank over time and makes it rumble and lose capacity. A standard flush is $150; a tankless flush is $429. See tankless maintenance.
- Replace: water pooling under the tank, rust in the hot water or repeated repairs on an older unit. Get a price online with our online water heater quote, and ask about up to $300 off water heater installation.
We pull the required permit for a water heater replacement. Considering a heat pump water heater? Puget Sound Energy, Redmond's electric and gas utility, offers $1,000 back on a qualifying heat pump water heater ($1,100 through its income-based Efficiency Boost program; pse.com, October 2026), and as a PSE Trade Ally we handle the rebate paperwork for you. Compare options on our water heaters page.
Drains and the sewer line: what we clear and what we don't
We clear indoor drains, including main drain lines from an indoor cleanout. We don't do sewer line work. That covers clogged sinks, tubs, showers, toilets, laundry drains and the main drain inside your home.
- One slow drain is usually a local clog that drain cleaning ($148, with the $99 dispatch fee charged separately) clears.
- A kitchen line that keeps clogging with grease is a good fit for hydro jet cleaning ($399 to $574).
- Water coming up in a lower tub or floor drain when you flush points to the main drain line. Tell us when you book; we clear it from an indoor cleanout.
If sewage backs up in the yard, the line outside is broken, or the sewer line needs repair or replacement, call a sewer contractor. Read more about drain cleaning.
Do you need a plumbing permit in Redmond?
Often, yes. Water heater replacements and new piping usually need a permit, and in Redmond the City issues plumbing and mechanical permits through its Development Services team. Homes outside city limits, in unincorporated King County, get permits from King County instead. That includes many homes in Redmond Ridge, Trilogy, Union Hill and on Novelty Hill; we can tell you which applies to your address.
You don't need to sort this out yourself. We pull the required permits for the work we do and schedule the inspection. Simple repairs, such as replacing a faucet or clearing a drain, generally don't need one.
Older and newer Redmond homes
Redmond has a mix of older houses and newer construction, and they tend to need different plumbing work.
- Older homes can have original water heaters, worn shut-off valves, older supply piping and drains that have narrowed with years of build-up. Leaks under sinks and slow drains are common first signs, and a whole-home plumbing inspection is a good way to see what is aging out before it fails. Our guide to plumbing problems in older Puget Sound homes covers what to look for.
- Newer homes and townhomes more often call us for water heater maintenance, tankless flushes, pressure-reducing valves, toilet and fixture repairs, and gas lines for a new range or generator.
Either way, the plumber explains what they find and gives you a price before starting.
How a Redmond plumbing visit works
- Book. Book by phone or online and tell us what you're seeing. If several drains back up when you flush, mention it.
- Your plumber arrives. Our plumbers work Monday to Friday, 8 AM to 5 PM, with same-day service when possible.
- Diagnosis. The plumber finds the cause and explains your options.

A recent Redmond plumbing job
In October 2026 a Redmond homeowner called about two slow-draining sinks and a toilet that whistled for a moment after each flush.
Our plumber cleared both sink drains and replaced the toilet's fill valve, which was causing the whistle. The visit carried our $99 plumbing dispatch fee, and the repair was quoted on site before any work began.
