comment Is it possible to use a hot water recirculation pump with a PEX home run system?
Yes, the biggest advantage to a PEX home run is in the combined material and labour savings. All you need to do is layout where the fixtures are going to be installed and where the header is to be located and then no more measuring is required. Just drill holes and pull the PEX.

comment Why would cold water be introduced into underfloor heating system?
In addition, depending on location/year of install it is quite often the case that in a residential application no back-flow devise would be installed as there is no chemical treatment being added to the heating system and risk of back-flow is minimal. In a commercial application there would be chemical added and thus a reduced pressure back-flow assembly would be required.

comment Why would cold water be introduced into underfloor heating system?
All I am saying is that I agree that the valve shown in the photograph looks to be a pressure reducing valve and this would be expected in this application. However a pressure reducing valves should not be considered as a form of back-flow protection as they are not designed as such.

A pressure reducing valve is not a cross connection device and should not be considered as one. See my answer for explanation as it was too long to be posted as a comment.

I would also question the location of the expansion tank within the system. See separate answer for explanation.

comment Should a kitchen sink S-trap be replaced?
Unrelated, you might want to pin that dishwasher hose up as high as you can within the cabinet space, trim any excess of the hose so that there are no dips or loops. This is recommend by almost all dishwasher manufactures.

comment How tight should threaded brass pipe fittings be?
No, I did not do any negative testing. I was taught this method throughout my apprenticeship. I have had leaks were I was not 100% confident on a joint and you lean from them. When you're plumbing you can't afford to have leaks as they are time consuming to repair.

comment How tight should threaded brass pipe fittings be?
@UNECS, I believe the question is asking about tightening tapered threaded fittings, such as NPT and not straight threads. With tapered threads, the threads make the seal as they bind into themselves and sightly deform making a labyrinth seal. The use of teflon tape and or pipe dope will obviously assist in providing a good seal (especially with bad threads) but their use is primarily to provide adequate lubricant.

@UNECS, the pump will pull water from the hot line back to the tank through a special tee fitting that bridges the hot and cold lines on the furthest fixture.
