"Very Friendly Plumbers who are familiar with the area. They pumped out cesspools every week down here in Mastic Beach by the bay. They are coming within the hour to pump our cesspool."

"I moved into my new home on 7/8 and knew I needed to replace the 20 year old hot water heater. The water was warm in the shower and brown. Originally, I planned on getting a tankless unit, but that was prohibitively expensive and not allowed in my community. Taking the next prudent steps, I secured my three estimates. Not only was AquaFlow the least expensive, but when I met Enrique, I knew I wanted to work with him on this project and all future plumbing issues. He explained what needed to be done, secured the tank from the supply dealer, and showed up at 9:00 AM promptly as promised. It was originally planned to be a two man job, but the other person couldn’t make it. Enrique did the entire job on his own. I was amazed. He worked until 5:00 PM. I asked why he didn’t just reschedule with me, but he stuck to the date and time he gave me. He also installed my new touch-less faucet and adjusted the cartridge in the shower and I now can take hot (not warm) showers."

"This was absolutely my best experience I have ever had with any company I have ever done business with. No need to look any further, this is definitely the company you will want to do your basement waterproofing . The work that is done and the professionalism of every member of this family run business will exceed your highest expectations. I am an avid researcher when it comes to finding the best company to do a job that I need done. I had an ongoing issue for years with water leaking into my basement. I had 6 top rated waterproofing companies(very well known on long island and beyond) come to my house and present me with why my basement was leaking and how the best way was to fix it. Each company had something different to say and all different ways to fix it. Then came the Napalitano Brothers(Sons James and Mike). These upstanding gentlemen separated themselves from all the other companies I had dealt with. They were polite, sincere, honest, genuine, well mannered, friendly, professional, knowledgeable, and patient. They presented themselves with pride in the work that they would be doing and ensured me that they would be able to provide me with a job that would satisfy me beyond measure. I cannot say enough about James and Mike( they both were hands on in doing the actual work for the entire job) they were true to their word and after meeting the patriarch of the family business, I can see why and where these young men get their loyal, honest and genuine qualities. If every business followed the business model and approach of how the Napalitano Brothers run a company, it would make it easy to pick a company to do a job. Good thing I am steadfast when it comes to doing research on a company and I take my time to choose what company I will let do a job I need done. I could not have made a better choice because there is no better choice out their when it comes to getting your basement waterproofed. Everyone says they are the best, but with the Napalitano Brothers you are actually getting the best. After you check out the other companies, let the Napalitano Brothers be the last one before you make your final decision and I will guarantee, you will do as I did and have them do the job. They will exceed your every expectation and put you at complete ease from start to finish, and even after with their follow up with you once the job is complete. Make the SMART choice which is the absolutely the BEST choice and have the Napalitano Brothers take care of your basement waterproofing. They will be my only choice and recommendation to anyone that I know that will need the services that they provide. Since the completion of the job, back in February 2017, we have had a good amount of rain with a few storms that brought tremendous rainfall and I can say with great happiness and satisfaction that my basement has not leaked even one drop. I am very grateful and thankful for meeting the entire family and workers and for having them do a"

"My gas water heater was 12 yrs old and needed to be replaced. Since I had prior experience with Mr. Rooter installing a water filter under my sink, I felt confident that the job would be done professionally. Rohan and Derick did an excellent installation of the Water Heater. The office was excellent too in informing me of their arrival time. I high recommend Mr. Rooter."

Sump Pump Installation questions, answered by experts

There are several indicators that your washing machine’s drain pump is bad, including incomplete cycles, water not draining, lack of spinning, a foul odor when the machine is running, and a loud grinding or buzzing noise when the pump is trying to move water down the drain.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Every three to four months, you should clean any dirt and debris off of your sump pump. You should also check the inlet screen (at the bottom of the pump) to make sure that it isn’t blocked. On top of that, you should deep clean your sump pump once per year—or hire a sump pump pro to do it for you.

A water pressure booster doesn't require special maintenance. Like any house system, inspections should be a regular part of your annual schedule. Check for leaks, faulty valves, pressure loss, and mineral build-up. Pressure loss could be a result of mineral build-up, and you can descale the system with a vinegar and water solution.
