"Jeremy from CFP Northwest Plumbing did an excellent job installing the plumbing for my washer. He was on time, professional, and made sure everything was done perfectly. He also cleaned up thoroughly after the job, which I really appreciated. I highly recommend Jeremy with CFP Northwest Plumbing, and I will definitely be using his services again in the future!"

"As an elderly customer my clogged drain, which turned out to be a broken sewer line, seemed a stressful situation. However the technician came pretty quickly and with the aid of his equipment, found the break, dug it up and repaired it. He was very courteous and helpful in explaining things, and I had great confidence in him. Would certainly recommend this company."

Customers say: Quick response

"Contacted Mike after waiting for the original plumber we called to cal back (never heard from him) . My daughter told us about My Guy had plumbed their bathroom. Mike told us he would be in Spokane on the 10th of March and that he could do a laundry room sink install in the afternoon. We sent him pictures of the old sink and the plumbing set up. He arrived as promised with all material in hand and within 4 hours he and his apprentice completed the job. The completed project was far better than we had ever hoped for. They did a total cleanup and removed the old concrete sink and did it all at a reasonable price. We would not hesitate to recommend Mike for any plumbing job."

"Riley was professional and friendly. After asking several questions he went straight to clean out the drain under our sink and gave us a primer on what can and can’t go down the garbage disposal and how to flush it ourselves. After 10 minutes of work he left. We had expected a bigger job, and possibly a new garbage disposal. Instead, he said he rather we call him if we ever need a plumber again, instead of charging us for 10 minutes of work. We appreciated his integrity and attitude, and will 100% call him if we have plumbing issues again."

"Scott arrived exactly on time and was very knowledgeable. He fixed the leak in my kitchen drain line quickly and efficiently. My only problem is their rates are based on a flat rate "book " charge. The job took less than 3 hours and the charge was over $600. I was informed of the cost prior to the start of work, so I'm not complaining I was over charged, rather the book pricing is very high. In summary, the work was good but the price was very high."

FAQs for sump pump or interior foundation drains installation projects in Spokane, 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.
