Best Backflow Preventer Replacement in New York NY

Very proffesional and was half the price of every other company  I called,  They came and took care of the backflow device the same day i called them and took care of all the paperwork as well.

UPDATE: after seeing the below review, the owner called me and tried to bully me into taking it down. Fun fact #1: mold concerns were never brought up until the owner called me trying to rationalize why his team wouldn't do the work. If there were mold concerns, then they should have communicated that there were mold concerns -- instead they said they had asbestos and lead concerns (in a building that's less than 10 years old). Sounds like he was fishing for an excuse. Fun fact #2: Bullying people is the behavior of a coward.

I stand by my original review. 100%

Issue: I have a leak originating somewhere under my tub/shower that drips onto the downstairs neighbor's bathroom ceiling anytime we run a bath. It was fixed by another plumber a month ago, but now the issue is back and worse than ever. I called ParkSet to diagnose/fix the issue based on the reviews I saw here.

They get one star because they actually showed up (and because I can't go lower than one star).

They lose 4 stars because:
1) when they originally showed up [a week ago] the plumber said he hadn't been told that he would need to open up the ceiling in the downstairs neighbor's apartment, and so he didn't have the tools necessary. Instead of going to get those tools [which he clearly needs to do his job], he insisted I reschedule. I did reschedule and waited another week.
2) when the rescheduled appointment happened today, a new set of guys showed up. My downstairs neighbor said they seemed pissed that the last guys didn't open up the ceiling and they said the first crew just left it for him to do. My neighbor says (and i quote) It seemed like he just didn't want to do the work. Then the new plumber got on the phone with me and said he doesn't have the tools necessary to open the ceiling. Sounds suspicious and lazy and super unprofessional. I asked him to go get the tools needed and come back because i'm not rescheduling a third time. Do these people not communicate with each other!? THEN I asked the plumber to have his supervisor call me.
3) A guy named Ronny called (his supervisor? I dunno) and said flat out that he refuses to have his guys open the ceiling because there's a baby in the apartment. I asked for more clarity on why -- dust? noise? He said because of possible lead and asbestos issues and he refuses to be liable for that. I explained that this isn't an old building; in fact, the entire complex was built less than 10 years ago. He was quiet for a second, admitted that there would not be lead or asbestos issues, but STILL refused to open the ceiling to diagnose the problem. What the actual f*ck.
4) as a possible alternative, the plumbers said they could remove the side panel of the tub and try to see if they can see any issues. I agreed. Then they called back AGAIN saying they can't remove the side panel because there's a rusty screw. Are you kidding me? I'm no expert, but even I know there are ways to remove rusty screws. But I guess that was also too much work for them because they just left without doing a damn thing.

How are these people even in business?! It's mind boggling to me.

STAY AWAYYYYYY.

Skilled professional with great communication and responsiveness. Actually did more work than necessary, replacing old parts to make sure the job was done right without any extra charge. You can see he cares a lot and takes pride in his work! EXCELLENT!!!!!!
