"He added a thermostatic mixing valve and expansion tank to my hot water heater. The solution looked good and functioned the way it was supposed to. He worked around my schedule and got the work done quickly."

"Our CPVC house piping had a lot of water hammer. After turning on the washing machine, I walked out for a moment, and then when I came back in water was dripping from the ceiling exhaust fan onto the washing machine. We have a two story house and they ran the hot water plumbing from the water heater in the garage through the laundry room ceiling. I removed the exhaust fan and could see water dripping from a tee way back beyond reach. The water hammer from the washer likely caused the fitting to start leaking. I turned the house water supply off and sent a message to Simpson plumbing through Angie's list. A lady from Simpson plumbing contacted me right away the next morning. She was courteous, but was having a hard time understanding what the problem was. Maybe I was giving too much information or something, but when the plumbers arrived later that afternoon they didn't understand what was going on. I ran through what happened again and showed them the wet spot on the ceiling. They had to cut an opening in the ceiling and we turned the water on and confirmed the leak. We moved my washing machine out of their way and they cut out the CPVC tee and replaced it with PEX. The piping was brittle so it took him a couple of attempts to get a straight cut which is why I called them to mess with it. After installing the PEX tee, we were leak free and at my request they provided a reference for the drywall repair. He also advised getting some water hammer arrestors installed on the supply lines to the washing machine to stop the water hammer, which I have since done."

"I needed to have a new faucet installed in the kitchen since mine was leaking for some time and also needed to have the drain under the sink replaced since I have a double sink and the water backed up when running garbage disposal David came a little earlier than scheduled which I was happy about he went right to work installing new faucet and a new pipe under the sink finished under an hour. He was very courteous and professional. I would definitely use All County again and recommend them .

FAQs for sump pump or interior foundation drains installation projects in Longview, WA

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
