"I was very pleased with my experience with Griswold Plumbing, they installed a new shower faucet/showerhead and later a water treatment system. They were prompt, very professional, and courteous going the extra mile when needed. I highly recommend Griswold Plumbing and won't hesitate to call them again."

"IT was great! I have never had a problem working with this company. The people (from the customer service reps to the billing to the drivers) have all been honest and realistic with expectations, answered all of my questions and never charged me more than what is advertised on their website. Patricia and Victoria have gone out of their way to return my many phone calls on the weekends too. You just don't get customer service these days anymore like the bullbag provides.They came when they said they would, did what they said they would do and did it professionally and pleasantlly. It is a pleasure working with such an honest and reputable company. Especially since the dumpster industry has not been know for this! These guys are definitely setting the bar high for all their competition."

"I had water in basement which caused mold. Was installing a new furnace and they saw the mold and said they could not continue with the installation until I had the mold treated, Boston called set up appointment to come out and give me a quote, he was very friendly and checked the house with me and explained that they would fog both basement and the house to kill mold. He set up an appointment for that week knowing it was important to get it done quickly so I could get the furnace installed. Aleksei came on time and walked through the house with me and started right away. He did the air test and called when he was done. They were able to get the test back within 3 days so I can get the furnace installers back to finish their work. I appreciate them getting the job done quickly and professionally."

Sump Pump Installation FAQs, answered by experts

3/4 HP is stronger than 1/2 HP. Horsepower measures how much weight can be moved and how fast, or the power needed to move 550 pounds one foot in one second. 1 HP equals 550 foot-pounds per second, so the higher the horsepower, the heavier the load it can lift. While 1/2 HP is a standard, powerful option, 3/4 HP has the extra strength to handle heavier, larger doors with ease.

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.

Sump pumps remove excess water from the lowest point of your home, which prevents flooding. When a sump pit fills with water, a sump pump pushes that water outside of the basin and into an exterior discharge pipe. From there, the water flows away from your home, so it doesn’t damage your foundation.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

DIY is possible for simple repairs. Professional services ensure proper diagnostics and long-term reliability.
