"I worked with Jesse to help with a clogged bathtub drain after I tried plunging it myself. I explained over the phone that I was dealing with backflow problems and each time I used the bathroom sink the water would end up back in the tub. Unlike another plumber who said they would need to charge me to snake both the tub and the bathroom sink, Jesse explained it would likely just need to be the sink and there is an issue in the shared drainage pipe. Jesse communicated clearly when he'd arrive and on his availabilites, and helped resolve the issue quickly and cleaned up after himself. He also gave me additional advice on how to manage my drainage issues in the future, and another toilet problem I had. Good guy to work with, and got the job done. Would hire again."

"Tony was very pleasant to work with. He accommodated my schedule, even with a big winter storm that had just rolled through. Tony and his team finished the project in about a day and a half and I couldn’t be more pleased! Not only was the job exactly what I needed/requested, but it was a very neat and clean job. His team respected my house and left the work area spotless. I will definitely call Tony if I ever need anything plumbing related."

"I had lost water pressure on Saturday and made a emergency call to a unknown company from google. I talked to a person immediately from Cassidy Plumbing and was told I would get a call from an employee in one hour. An employee called and would come over in 15 minutes. I was amazed at the response time. He check out my water system thoroughly and told me that I wasn't getting water in the well tank causing me to lose pressure but also I was not getting any pressure straight from the well either. It was either the water pressure tank with the pressure switch or the water pump that was causing this problem. The pressure gauge was also broken. He explained fully what needed to be done, the price for each issue and since he was not able to do anything until Monday, I was first on the list.
Cassidy Plumbing called me in the morning and told me that they would be their in one hour. They came promptly and went to the well tank first and found out the pressure switch had corroded and the well tank was also not doing it's job. The tank was about 15 years old and the switch was more than 25 years old. I was told and saw everything that needed to be replaced and the price. When replacing the valve close to the water filter housing the piping broke off and upon looking at it this was corroded too! I was able to get a discount for the water filter housing since they were working on that section of piping and it was unexpected. Afterwards they tested the water pressure to make sure all was working and that the register near the pressure switch was functioning.
My water room is the size of a closet. Inside is the water heater, water softener system (tank for salt and two tall cylinders), electrical box, telephone box, cast iron plumbing for toilet and the well tank. It was tight to say the least and they did a neat job of putting everything together and cleaning up.
I have had to replace my well pump and another time the electrical wiring to the pump and both these companies could not compare to the professionalism and services that Cassidy Plumbing and Heating."

Drain Cleaning FAQs, answered by experts

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

Yes, frozen pipes can cause a toilet to stop working correctly. If the pipes are frozen, water cannot flow, which can lead to two main problems. First, the supply line to the toilet tank may be frozen, which prevents the tank from refilling with water after you flush. Second, the drain pipe itself can freeze, blocking water from flushing away. As a temporary solution for a non-refilling tank, you can manually add water, but this is not a long-term fix. To clear a frozen drain pipe, you can try pouring warm water into the toilet bowl or tank and then flushing, as the warm water may help thaw the ice blockage. Ultimately, the best course of action is to unfreeze the affected pipes to restore your toilet to full functionality.

It is not advisable to use drain cleaner in a washing machine. Drain cleaners contain harsh chemicals that can damage the internal components of your washer, including rubber seals, hoses, and even the drum. These chemicals can also react with any residual detergent or fabric softener, potentially leading to noxious fumes. If your washing machine is experiencing drainage issues, it's best to address the problem directly by inspecting and cleaning the lint filter, checking for clogs in the drain hose, or seeking professional repair services. Using drain cleaner in a washing machine is a risky solution that can cause more harm than good.
