Sump pump repair and replacement in Kirkland, explained in 30 seconds
Green House Plumbing and Heating repairs, replaces and installs sump pumps, battery backups and high-water alarms for Kirkland basements and crawl spaces. We are based at 12040 98th Ave NE in Kirkland (98034), work Monday to Saturday from 7 am to 9 pm, and offer same-day appointments when available.
Kirkland gets about 40 inches of rain a year, and November is usually the wettest month. That is when a weak or stuck pump shows up as a wet basement. Most failures we see come from a stuck float switch, a worn-out motor, a clogged or frozen discharge line, or a power outage during a storm.
We test the pump under load, check where the water actually goes, and give you an upfront price to repair or replace.
Sump pump not working and water is coming in? Do this first
These steps can buy time and protect your belongings until we arrive.
- Stay safe around water and power. Do not step into standing water near outlets or the pump. Turn off power to the area at the breaker if you can do it from a dry spot.
- Check the plug and breaker. A tripped GFCI outlet or breaker is a common reason a pump stops.
- Free the float. With power off, check that the float can move up and down freely and is not caught on the pit wall or cord.
- Move valuables up. Lift boxes, electronics and rugs off the floor and away from the pit.
- Call us. Tell us if the pump hums, runs nonstop or does nothing. That helps us bring the right parts.
Sump pump warning signs we see in Kirkland
Match what you see to the likely cause and how we fix it.
Pump runs but water keeps rising
- Likely cause
- Clogged intake screen, stuck check valve, frozen or crushed discharge line, or an undersized pump.
- How we fix it
- We clear the line, replace the check valve, and size the pump to the inflow you actually get.
Pump runs nonstop or cycles every minute
- Likely cause
- Float switch stuck on, failed check valve letting water fall back, or a pit that is too small.
- How we fix it
- We replace the switch or valve and, if needed, adjust the pit or pump setup.
Pump hums but does not pump
- Likely cause
- Jammed impeller from debris or a failing motor.
- How we fix it
- We clean the impeller and test the motor. A burnt motor means replacement.
Loud grinding or rattling
- Likely cause
- Worn bearings, debris in the impeller or a loose discharge pipe.
- How we fix it
- We secure the piping and repair or replace the pump.
Basement flooded during a power outage
- Likely cause
- No battery backup, or a backup battery that has run down.
- How we fix it
- We install a battery backup pump and a high-water alarm, and test both.
Water pooling near the foundation outside
- Likely cause
- Discharge line ending too close to the house, so water cycles back into the pit.
- How we fix it
- We extend and reroute the discharge to a legal, safe outlet away from the foundation.
Repair or replace your sump pump?
A pump that fails in a November storm costs far more than one replaced on your schedule.
Repair usually makes sense when
- The float switch or check valve has failed
- The impeller is jammed with debris
- The discharge line is clogged or disconnected
- The pump is only a few years old and the motor tests fine
Replacement usually makes sense when
- The pump is around 7 to 10 years old or more
- The motor hums, overheats or trips the breaker
- It cannot keep up during heavy rain
- You have no battery backup and the basement is finished
| Option | Best for | Notes |
|---|---|---|
| Submersible pump | Most Kirkland basements | Quieter, sits in the pit, handles heavier inflow |
| Pedestal pump | Small or shallow pits | Motor above the pit, easier to service |
| Battery backup pump | Finished basements, storm outages | Runs when power is out, needs battery checks |
| High-water alarm | Every sump pit | Warns you before water reaches the floor |

Why sump pumps work hard in Kirkland
Rain, slope and older drainage all play a part.
Lots of rain, mostly in fall and winter
Kirkland averages about 40.6 inches of rain a year, with November the wettest month at around 6.4 inches. Test your pump before the rain starts each fall.
Hillside and lakeside lots
Homes on slopes such as Finn Hill, Market and Houghton, and lots near Lake Washington or the Juanita and Forbes creek areas, often see more groundwater against basement walls.
Storm outages
Fall and winter windstorms can knock out power just when the pump is needed most. A battery backup pump and alarm are the simplest protection.
Where the water must go
Sump water must not go into the sanitary sewer under Kirkland code. It should discharge to your yard or approved storm drainage, well away from the foundation.

How long does a sump pump last in Kirkland?
Many sump pumps last around 7 to 10 years. Pumps that run often during long wet seasons can wear out sooner. If yours is near that age, replacing it before the November rains is cheaper than cleaning up a flooded basement.
Can you replace a sump pump the same day?
Usually, yes. A like-for-like replacement typically takes 2 to 4 hours, and we offer same-day appointments when available, Monday to Saturday, 7 am to 9 pm.
Can my sump pump drain into the sewer in Kirkland?
No. Kirkland Municipal Code 15.36.010 prohibits discharging ground water, surface water and subsurface drainage into sewers built only for sanitary sewage. We reroute sump discharge to the yard or approved storm drainage.
Do I need a battery backup sump pump?
If your basement is finished or you store anything valuable below grade, yes. Power outages often happen during the same storms that raise groundwater, which is exactly when a pump without backup stops.
Why does my sump pump run all the time?
Common causes are a stuck float switch, a failed check valve that lets water fall back into the pit, a pump too small for the inflow, or a discharge line that is blocked. We test each one.
How often should I test my sump pump?
Test it every fall before the rainy season and a few times through winter. Pour a bucket of water into the pit and make sure the pump starts, empties the pit and shuts off.
Do you install sump pumps in crawl spaces?
Yes. Many Kirkland homes have crawl spaces that collect water. We install pits and pumps sized for the space and route the discharge away from the foundation.
Which areas near Kirkland do you serve?
All Kirkland neighborhoods, including Juanita, Finn Hill, Kingsgate, Totem Lake, Rose Hill, Houghton and Bridle Trails, plus Bellevue, Redmond, Bothell, Woodinville and Kenmore.
