Monty showed up on time and kindly walked me through the service needed to fix the low water pressure in the shower. He quickly understood how to fix the problem and was incredibly efficient and thoughtful throughout the process. He did a great job, and I am very satisfied with the results. Thank you for the excellent service!

My wife and I live in a 120 year old house and when some old metal pipes backed up and started leaking we called the right people. Cameron came out and did a thorough inspection and clearly explained what was going on. Next morning, came out removed the old pipes and installed new ones. Problem solved and we couldn’t be more satisfied with his help.

OMG! Fantastic and quick service!  Found a wet spot in the basement ceiling. Cameron was out the next day shortly after we called, found the problem, gave us our options, and began work immediately. While we were at it, we had our kitchen faucet replaced!  Cameron was very nice, very thorough, and stopped to give our dog a pet each time he went in and out to his truck.  Highly recommend.

Signs Your Sump Pump Needs Immediate Attention

Sump pump problems often show themselves before a full failure happens. Here are the common signs that indicate the need for repair.

  • Pump not turning on
  • Constant running without shutting off
  • Loud grinding or rattling
  • Water remaining in the pit
  • Frequent tripped breakers
  • Slow or weak drainage
  • Foul odors from the pit
  • Visible rust or corrosion

Seattle’s rainy season puts consistent demand on sump pumps, sometimes for weeks without much of a break. If you notice any of these signs during a period of heavy rain, addressing the issue quickly can prevent a much bigger mess in your basement and save you from a far more expensive cleanup later.

What Usually Causes Sump Pump Failure

Mechanical wear is one of the most common reasons sump pumps stop working properly, especially in systems that have been in place for several years without regular maintenance. Internal components like the impeller or motor naturally degrade with continuous use, and once wear sets in, the pump has to work harder to move the same amount of water, which often speeds up the timeline to full failure.

Clogged or blocked intake screens are another frequent culprit. Debris, sediment, and small particles can accumulate over time, restricting water flow into the pump and reducing its overall effectiveness. This kind of buildup is especially common in older systems that have gone a long time between inspections, and it often mimics the symptoms of a failing motor even when the motor itself is fine.

Power issues and float switch problems round out the most common causes we see. A stuck or misaligned float switch can prevent the pump from activating at the right time, even when the motor and other components are working properly.

Combined with occasional power interruptions during Seattle storms, these issues are why homes without backup power sometimes experience pump failure at the worst possible moment, right when the pump is needed most.

How Our Sump Pump Repair Process Works

When you call us about a sump pump issue, we start by asking a few questions to understand what you are experiencing, which helps our technician arrive prepared. Once on site, we inspect the entire system, including the pump itself, the float switch, the intake screen, and the discharge line, to identify the actual source of the problem rather than guessing based on a single symptom.

After pinpointing the issue, we explain what we found in plain language and provide an upfront price before any repair work begins. If the pump can be repaired rather than replaced, we will walk you through that option, honestly, including what to expect from the repair going forward. There is never pressure to replace a system that can be reliably fixed instead, even if replacement would mean a larger job for us.

Once repairs are complete, we test the pump thoroughly to confirm it activates properly and drains water as expected. We also flag any additional concerns to watch, particularly if the system is older and may need replacement sooner rather than later, so you can plan rather than be caught off guard during the next storm.
