Hello, We purchased a 1966 built condo recently and got a Culligan softener and RO system installed due to the extremely hard water in Morristown NJ. They installed PEX pipe work to connect everything to our existing copper pipes. After the installation we had an issue where a toilet flush or running dishwasher or running washing machine caused loud vibrations in the shower line while the shower was running. A technician visit to check on the softner system resulted in them saying that the PRV is broken.

They installed a like to like replacement WATTS LF25 AUBZ3 PRV saying that the pressure is too high at 90-100 in our pipes and the softener unit can take upto 80. The PRV is set to 75 as of now.

The new form of this problem we now have is also in the shower - but a vibration in the pipes at a certain mix of hot and cold water. The toilet flush doesn't lead to vibrations now! The culligan team claims that our shower valve is faulty and that they cannot touch other plumbing in the house to install hammer arrestor devices and so on. Really at my wits end here and tired of dealing with this. What do you experts think?

do you have access to the pipes ? basement ?
Yes - the softener, RO system, PRV and pressure guage are all in the basement attached to our unit.

The hot water boiler and other hot water system and the building mains are in the utility room to which I don't have access to.

Yes we have access
what you do = have a few common sense people stand by the piping's. have someone do whatever it is to make your issues. they listen for the noises. when narrowed down, repeat the issue and have yourself or whoever hold onto the piping to see if that makes the noises change. your issue sounds like the pipes are not secured as they should be.
