"Paul has always done excellent quality work for me. Really happy with his work and professionalism. Highly recommended"

"Over charged my father for a backwater valve repair gave him an invoice with no specific breakdown on the job that was done. Had to request for a breakdown invoice Charged him $4k for a 4 hour job that was not done properly as the basement re flooded again. Gave me a run around for 3 weeks to get a breakdown on the invoice. As you can see from the screenshot.poor work Watch out for these guys. They don’t get the job done and they overcharge. We had to also pay for their the permits they were suppose to already have. And also pay for the rental truck and fuel! Second image is from the basement re flooded again after work was done"

"Rob had recently replaced my kitchen and bathroom faucets and I called him to see if he could now replace my gas water heater. I was happily surprised when he said he’d be out within a couple of days and I was REALLY pleased with his estimate. For both jobs, Rob showed up when he said would and was both fast and efficient. He’s a great guy - dependable, reasonable, professional and focused on providing good service to his customers. Rob is my “go to” plumber from now on!"

"Topic is a home water supply Shallow Well which operates with a shallow well jet pump + pressure tank installed in the basement. I had been collecting parts over the summer, as I knew the original to house jet pump would go out soon some day and with covid parts are hard to get quick, so started collecting ahead of time. Glad I did as the pump started leaking, from the housing. Replacement needed. Not an emergency but time to get it replaced. Was a ticking clock as it also looked like the pump was twisting putting stress on piping as original owner did not mount it and other fittings had large amounts of corrosion on them. I supplied these parts for the job: new 1hp jet pump, 44 Gal. pressure tank with T package, water filter housing, brass fittings, brass check valve, brass ball valves, 1" copper pipe and some copper fitting, and 2x10 pressure treated board to mount the pump/board to the floor with concrete anchors. Called up Sila on 10/14, master plumber Dave was available on 10/16 to come quote the job of installing what I supplied and misc. parts still needed. Talked with me and received my requests for specific design wants and he supplied his opinions & additional ideas and other options like wall mounting of water filter, sensor shutoff option and different water filter all together and we worked out the plan, did not do the different filter or sensor though. Talked about brass pipe and fittings at the pump up to the pressure tank and we agreed what I had purchased was good and would last a lifetime, vs copper all the way which would still last a long time. Quoted $2800 with water filter bypassing and $2600 without the water filter bypassing. Job was scheduled for 10/22. Quote was high level line item as listed here. Came a bit late on 10/14, due to an emergency call, no big deal Dave called to let me know. Was on time for installation on 10/22, 7:30am. Two workers on Job (Dave + 1, sorry I’m horrible with names +1 was an electrician and was helping Dave) Job took ~ 8 hours to finish. What was not able to be completed: Was not able to replace old original check valve. Well started to suck air when old was started to be removed, confirming there is no foot valve on the line or a broken one, so old check valve was kept. Concern was not being able to recover from air going down the well pipe causing priming issues. At this point the job would require a well expert and was not able to be replaced by Sila. What part of job was mis-understood: Mounting of jet pump to board/floor. Ended up missing the concrete anchors to start and installing after the fact with a different method. Made it more difficult to mount the pump and did scratch the rust proof paint. But it got done. Nice and sturdy. What was complicated on the job: Something that should have not been an issue at all went wrong. I had purchased 1” brass unions. There were two unions installed. One was found to be causing leaks during the initial job installation. This caused extra rework during the initial job. After job completion and area dried with a fan, it was found that both unions were leaking. The original one that had issues in the initial job and the 2nd one. One is pre pump and one is post pump. Called Sila office on 10/23 and told them what was happening, Dave’s earliest availability to come back was was 10/26. He was on time on 10/26. Dave stated that 1 union was giving trouble and replaced it with one spare that I had also purchased. When looking at the 2nd union again he was not able to get it to seal and he made the call and changed the design to direct copper connection and no union, I did not object as at this point just wanted the job done. No More leaks on that location, but also no ability to easily break the connection for future maintenance. When left no leaks. However, after using water for a while the 1st union started leaking again. Texted Dave direct with a picture and said he could return on 10/28 and I requested him to bring a union from his supply. Arrived when he could with ~ 1hr notice and replaced the union with one of his. When looking closer at the issue unions that I had purchased it was found they were cracking. Summary: I’m a novice in pluming, reason for calling Sila. I wish Dave would have noticed the poor part / crack issue and replaced unions from his stock on day 1. I was trying to save time by collecting parts over time and ended up causing issues. Dave knew he was working with brass and seems like he did not have backup stock on site incase of issues. Wish he did as I’d have two unions… and he would not have had to come back twice to repair the leaks. The call was made to not use the brass ball valves I purchased so it was clear that my parts were recommended to use but not absolute. Overall Dave and team did a great job, it’s clean, organized, valves and drain spickets installed nice and logically, filter is at good height, job completed like I asked and planned with Dave, except for the above jet pump mounting, union issue and check valve replacement discussion above here. Dave and team was professional and focused to get the job done. Thanks Dave for your hard work. Reason for Rating: I am giving this job an A rating based on the end result, Sila stood by the workmanship and resolved the issues that arose. That is a sign of a great company. If I would not have supplied the couplers that issue would not have happened ultimately and the check valve & well priming issue was just out of reach and would have required a well specialist to complete. The pump mounting was probably just lost in the large amount of details we had discussed, again it is mounted sturdy."

"I hired Merrimack Valley Plumbing to install a boiler in my home, and my experience was overwhelmingly disappointing. While the boiler functions, the installation process and quality of work raised numerous red flags. I want to share my experience to help others make an informed decision when considering this company. Installation Issues Code Violations: The exhaust is less than 3 feet from the gas meter, and the holes drilled in the joists for intake and exhaust are less than 2 inches from the bottom, both of which do not meet code requirements. Improper Venting: Both the exhaust and intake vents are installed too close to the ground (not meeting the 12-inch clearance required for expected snowfall) and are too close to each other (less than the 12-inch separation required). Unsealed Penetration: The hole drilled in the siding was left unsealed, creating a potential entry point for rodents. Condensate Drain Issues: The installed condensate pump is leaking and wasn’t tested. Additionally, rather than a permanent drain installation, they daisy-chained it into a pump for a portable air conditioner. Wiring Errors: The zones for the primary bedroom and second floor were wired backward, causing overheating in both areas. Missing Outdoor Sensor: The outdoor temperature sensor, critical for proper operation, was not installed. No CO Alarm: A carbon monoxide alarm was not installed, which is essential for safety. Unprofessional Workmanship: Trash, including a metal duct pipe, was left in the crawl space near live electrical wires. Process Concerns Permit Delays: The company failed to file permits before starting work. I only discovered this after contacting the town permitting office myself. Mismanagement and Delays: The project stretched far beyond the promised timeline, with repeated excuses about missing parts and limited crew availability, despite prior assurances that the job would be completed in two days. Broken Promises: They claimed a project manager would take measurements in advance to ensure a smooth installation, but no one came. Additionally, they rescheduled initially, promising a larger crew, only to send a single plumber on the first day. Misinformation and Deception Throughout the project, I encountered multiple instances where Merrimack Valley Plumbing provided misleading or false information: - They lied about the dates permits were filed. - They claimed delivery issues caused delays, though they should have anticipated these based on the advance photos provided. - They repeatedly shifted blame rather than taking accountability for the delays and issues. Overall Experience While the boiler itself works, the installation was riddled with code violations, safety oversights, and poor workmanship. Additionally, the company’s lack of transparency and repeated dishonesty made an already frustrating situation worse. I would not recommend Merrimack Valley Plumbing to others. Their lack of professionalism, disregard for safety codes, and failure to take responsibility for their mistakes created an unnecessarily stressful and costly experience."
