"We needed a plumber to fix a kitchen water leak. Chris called almost immediately and scheduled an appointment. Ken came and assessed and repaired the problem and installed a new faucet. He also answered some questions we had on a few other potential issues and all the services they provide. We will definitely be calling CW Cummings for future plumbing needs and highly recommend them. Prompt, professional, reasonable."

"Put in new shower heads that met our needs. John was on time, gave us a fair price, left area very clean and wore booties over his shoes. Very congenial person. When he came to give us an estimate we explained our needs and he gave us choices as to how it could be done and gave us the pricing. Work was done as specified and pricing. Would recommend him and we would certainly hire him again.."

"Preston called less than a minute after I submitted my request. He quoted a price and an arrival time and delivered on both. He was cheerful, funny and engaging, a real delight to work with. He fixed the clogged drain and gave us advice on how to avoid the problem in the future. We'll definitely call Preston next time we need a plumber!"

Plumbing FAQs, answered by experts

When it comes to PEX versus copper, you'll find that many plumbers prefer PEX, which doesn’t corrode or allow for sediument buildup and is less likely to burst under freezing conditions. PEX is also flexible, so your pro won’t need to install joints to create certain angles. Provided it’s up to local codes, your plumber can also snake PEX through smaller holes in the wall without making additional cuts.

No, you can’t convert a gravity-flush toilet to a pressure-assist toilet. Pressure-assist toilets include a tank-within-the-tank, and a standard gravity-flush toilet doesn’t have a capability to include the additional tank. If you want the benefits of a pressure-assist toilet, you’ll have to make the investment in a new one. 

You cannot leave the sewer cleanout cap off. Leaving it off can be dangerous and costly for you. If you need help getting the right sewer cleanout cap or adding one to your system, reach out to a local pro for advice and professional help to ensure the cap is installed correctly. 

Pipes are connected in a bathroom by a 3/4-inch to 1-inch line running from your water meter into your home. The line then splits, with the hot water line going to your water heater and the cold water line running into your home. The cold water line leads to the 1/2-inch water supply lines for your home’s toilet, tub, and sink. The hot water line runs from the water heater to all sinks and baths.

Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.
