Dual port valves
Guys,
I have a site where a lot of units are fitted with dual port valves. However, only one prv is fitted and the second port is blank. The second port is not blocked off, just a plastic cap. I don't see this as good practice though, as that open port could seep refrigerant over time. It can't be blanked off properly, as then you would be capable of isolating the existing prv which is against pressure vessel regs.
What are your thoughts on this? Seems a cheap skating exercise to me.

Re: Dual port valves
Did someone remove the 2nd prv's for testing and forgot to refit? Stick new valves in the spare ports, much safer.
Mostly found in the southern part of this green and pleasant land.
