"Reliable is awesome, they came right out and they replaced my hot water tank in 6 hours. Gerry really knows what he is doing. The best licensed plumber ever in my 30 years living here. He explained to me, If the hot water unit is not installed a certain way that it could fail in only a couple of years. Always go with a pro that’s what Reliable is ."

"Snake the Drain plumbing was amazing. I am so glad that my husband and I opted to use this company to fix out hot water pipe issue. Our primary bathroom had a leak that effected several rooms in our house. Louie and his team quickly responded to our call and immediately solved our plumbing issue. Armand even came back the next day to check in on the work that was completed. I am looking forward to being able to work with Snake the Drain plumbing again. Their customer service, timeliness, and fair prices truly qualify them as a top notch company."

"This family owned company exceeded my expectations. I hired them to address a septic problem. They arrived on time. Their quote was reasonable. I lived out of town and they kept me in the loop through out their work Even used FaceTime to show me problems as they arose. They even followed up with me the next day to ensure that everything was working as promised. They really cared that the job was done correctly and to my satisfaction. I would recommend them to anyone with a simple or complex plumbing issue and needed someone they could trust."

"I called them because my roomate was complaining of a backup in the sink and the tub.  Since he was complaining of these at the same time I assumed it was an issue with the pipe going to the cesspool as I've had an issue with it before (and yes, I used the same company both times).  When they showed up, they looked at the issue and determined it wasn't a problem with the pipe and actually helped me discover and fix the problem (the stopper in the tub had fallen into the drain and blocked water flow).  They even gave me some tips for the sink.  This was a great example of a company going the extra mile to help me solve a problem even though it was outside their area of responsibility.  Very happy with them, will use them again if needed.

Plumbing questions, answered by experts

The humid climate and coastal weather in Islip directly impact plumbing. High groundwater and storm surges create hydrostatic pressure, increasing the risk of basement flooding and sewer backflow. Salt air accelerates corrosion on exposed outdoor fixtures. You must bury water supply lines at least 36 inches deep to meet NY state code and prevent winter freeze damage. Insulate pipes in unconditioned spaces to stop summer condensation and winter freezing.

Helpful?

Cosmetic plumbing updates, like replacing a faucet, finish quickly and bypass local permit requirements. Functional work, such as relocating drains, requires full permits and mandatory inspections that extend project timelines. In Islip, functional upgrades that increase water usage demand strict septic system reviews to ensure proper load sizing. Opening walls for functional repairs in older NY homes also triggers strict lead paint regulations and potential flood zone compliance measures.

Helpful?

Leaving hoses attached to outdoor bibs through fall prevents proper draining and causes freeze damage at the wall. Ignoring unconditioned crawl spaces in Islip leaves exposed pipes vulnerable to winter freezing. If you rely on well water, failing to monitor mineral hardness accelerates scale buildup inside your plumbing and water heaters. Flushing heavy paper products or grease into older cesspool systems causes rapid system failure and hazardous home backups.

Helpful?

Watch out for quotes that omit local permit fees for substantial plumbing work. Contractors who claim permits are unnecessary shift significant legal risk onto you. A quote lacking a valid local license number is a serious warning sign. Be cautious of vague plans regarding cesspool decommissioning or municipal sewer connections. Legitimate professionals in NY will always include post-completion inspections in their plans to ensure the work meets local safety standards.

Helpful?

Underground water service lines require proper bedding in Islip due to sandy soils and mandatory frost depth requirements. Improper installation leads to pipe settlement and freeze damage. Sump pump discharge routing is another sensitive area for plumbing; directing discharge into the sanitary sewer violates local ordinances. Connecting to municipal sewers or decommissioning cesspools demands exact compliance. Always secure local permits for major work to avoid serious resale and safety issues.
