"5 star + company ¦ plumbers (2 sent for job) were professional, hard working, knew what they were doing, cleaned up when job was completed and very respectful.. The workers drive a fully stocked company van so were able to complete the job the day I received my troubleshooting and quote. Company name and phone number are proudly advertised on van. Geremii, (owner) you have a terrific business and answered all of my questions so I was never in the dark about the work that was done. I recommend them to everyone!"

"Excellent service. I received a prompt call after first contact. Arthur answered every question I had to understand what needed to be done without referring me to anyone else during the call. All work was completed as promised in a timely manner."

"These people are competent but their ethics are highly questionable. I posted a job description on yelp and tendered offers from many plumbers John's Plumbing replied and agreed to do the work for a specified price. The work consisted of two parts. After they had done the first, they told me it was best to wait until the bathroom wall was tiled before doing the second and assured me they would return. After tiling was complete and I requested they come and finish the work they surprisingly told me it would cost another $500. Miscommunications can of course occur but in this case the scope of work was given to them in detail and clearly included both parts. This is not only highly unprofessional but outright dishonest. While they may be competent I would advise people to consider choosing another company for their plumbing needs that has a higher ethical standard."

"Wesley was fantastic! We were hoping to be able to extend the gas line from the fireplace to the stove but the piping was too small there to accommodate the stove we purchased. While he said it could be done, and was significantly less expensive, it may not be able to provide the 'power' the stove required. We chose to do it the right way, not the 'cheap' way, pricing was still reasonable for the amount of work that needed to be done. Highly recommended!!"

FAQs for sump pump or interior foundation drains installation projects in Pasadena, CA

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.
