Hi,
I was doing some research on low flow and I noticed that most PRVs have a strainer that you are supposed to clean out once in a while.
I've located my PRV (just after the meter box). The tag says F1201C pressure reducing valve, CSA B-356, size 3/4", range 25-75, max temp 180F, max inlet 300PSI. This is some made in Taiwan PRV, not the more common Watts, etc. brands.
After Googling all sorts of PRV pictures, I still cannot figure out if the nut at the bottom of the PRV is the strainer or something else entirely (see picture, yellow arrow ). I want to clean the strainer if it has one, but don't want to open the nut only to find out it's not a strainer and I've totally compromised the PRV. Is anyone familiar with this PRV and can tell me definitively if that nut opens up a strainer I can clean?
That aside, I am just realizing through my research that my PRV was not installed very well. Apparently there is supposed to be 2 union joins so the PRV can be replaced easily if needed. How would a plumber replace this one? Would they have to cut the PVC connection? If I ever replace the PRV, can I ask that 2 union joints be put in? Is there a union join for the PVC connection side or am I stuck with this configuration?
Last question. The PRV is located outside in a covered box, but should I worry about it freezing?
Thanks so much for any expertise or insight you can provide.
