Our expert technicians analyze your water quality and recommend the perfect solution, from water softeners and filters to reverse osmosis and UV disinfection systems. Enjoy cleaner, healthier water free of unwanted minerals, chemicals, and bacteria.
"Second time i had an issue with then over charging me. I had setup an appointment for salt delivery and to check the water filtration system. In between the scheduling and the appointment the water filter issue resolved itself, they insist on still charging me $150 for the service visit ex the salt delivery. Keep in mind one technician came out to put salt in the water softener and “check” water system. I never got a bill or adked to sign anything, they just charged the card on file. Random charge just shows up on my credit card. Borderline fraudulent activity here. Would be very careful using them if you are a new customer. Further there filters are custom so you need them to change the filter every 4-6 months which you can only use them and they charge near $500 for this. Be really careful with this company! Not to mention they don't tell you, your water pressure goes down by 40% when u install this stuff!"

"On April 21, 2018, Ernest Serghi of American Plumber, LLC gave an estimate to replace the existing 1.5” underground gas line from the gas meter to the pool heater. This line is buried 30”. I told him that I wanted a 1.5” poly gas pipe buried 18” which was specified by the Holmdel plumbing inspector. He agreed to this and I signed the contract. On May 9, 2018, Ernest came to do the job and dug a narrow trench with a small hand-operated trenching machine and rolled out the yellow poly gas line, I measured the depth immediately and told Ernest that it was only about 12” deep and I wanted it 18” deep as he had agreed to. Ernest said the Code only requires a 12” depth and refused to dig the trench deeper. Ernest did the job in just 2 hours since he did not dig the trench 18 inches as he had agreed to. I have photographic evidence that in one area the gas line is only 9 inches deep. This is a violation of NJ Fuel Gas Code 404.9 that specifies a minimum burial depth of 12”. On May 10, 2018, the Holmdel plumbing inspector looked at the job quickly and approved it. However, he failed to measure the depth of the gas line and did not realize that it did not meet the minimum burial depth required by the Code. In the contract job description, Ernest did not specify in writing the 18” burial depth of the gas line that he had agreed to. I should have required this wording since Ernest did not honor our verbal agreement. I have contacted American Plumber, LLC several times in an attempt to have them correct the code violation and adjust the contract price to reflect the work that was actually done. Instead of trying to correct their error, American Plumber, LLC is demanding payment in full and filed with the Clerk of Monmouth County a Notice of Unpaid Balance and Right to File Lien against my property. I have filed complaints about this unscrupulous and dishonest contractor Ernest Serghis of American Plumber, LLC with the NJ Department of Consumer Affairs and Better Business Bureau."
