"The work done wasn’t what is shown above, but that was the closest option. The plumbing was checked throughout the house. He inspected all sink and tub/shower drains and valves, the sump pump, hot water heater, and main water shutoff. He explained any possible problems that could be changed. He was pleasant and helpful. I would recommend him and request him for future issues."

"..I understood that there would be overtime charges because of weekend and the time of day. I shut the water off to the house and didn't want to wait overnight and try to get someone on a Sunday. The plumber arrived earlier than some of his other scheduled jobs to take advantage of what sunlight remained. He explained that the pvc connection was made incorrectly and that was the cause of the leak. He removed the section of pipe that ran from the service entrance shut-off valve to the pipe that led to my backyard hose bibs. The section he removed contained another valve that shut water off to my backyard. 
He was installing the new section when I noticed that it didn't contain the valve to shut-off water to my backyard. (I usually have the water shut-off to the backyard except when I need it because I don't want to have to shut off water to the house when repairing leaks in the underground pipes or the hose bibs.) When I questioned the plumber about  this, he muttered, "customers!" and went to his truck for a valve which he then installed.
My problem with Garrett is that the quality and professionalism you get when you call for service varies with the person who shows up for the job. I've noticed this from past experiences. For that reason, I'm looking for a plumber with consistent quality employees. For this job, I believe the plumber was probably well qualified, but I believe that he should have installed the same type of hardware that he removed (the shut-off valve) before proceeding.

"He provided great service during my project to replace all 3 toilets in my house. My toilets were awful when I moved in even flooding my house which was an extra project itself but with Fermins help from costa plumbing I didn’t have any plumbing issues with my toilets any more."

"Kyle & Max did a great job with our home. They were very professional and explained everything they did. They kept their work area clean and organized. They also made sure if we had any questions or concerns that they would be just a phone call away. My house feel stable and the floors are even now. I would highly recommend Alpha Foundations"

"Apex Plumbing employees, James and Zach, came to my house to repair a water leak that stopped all water service to my house. James came and cleared the lawn covering my pipes. Then Zach came, located the leak and replaced the water pipe serving my house. Unfortnately, The meter showed a continuing leak. James crawled under my house and found an unknown second leak. They eliminated that pipe leak under my house. I now have full water service to my house with no more leaks. Thank you Zach and James for a complete repair of known and unknown leaks. Good job!"

"We dealt directly with Steve. He 100% knows what he's doing. The city hires him for all kinds of things. We checked out quite a few competitors for water softener prices. Really no comparison. We ended up buying a water softener on Craig's List and then purchased the whole house filtration. Steve exceeded our expectations on the installation. YES I would use him again. Very knowledgable and competitive pricing."

"Great. Fixed intire system and installed new control unit. Did not try to upsell me when I was willing to replace anything that looked bad. One sprinkler head that they didn't replace started to work but eventually is now not working but otherwise I love the job he did. However. Only complaint I had was delays which were not the company's fault but was tied up at the house due to not communicating back ups due to weather and homeowner add on to existing job causing delays and I knew that was the case I just wanted a call to confirm so I could have planned my days better but I loved his knowledge and blue collar work ethic and will definitely use this company again."

FAQs for sump pump or interior foundation drains installation projects in Largo, FL

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.
