So how does that work?
The pump is mounted right on the hot water tank and some sort of non-electric cross-valve at the bath sink? Does it just continually leak water from the hot line to the cold or ... ?

Your unit has one pump now, likely right next to your fresh water tank, it has a built in pressure switch that turns the pump on when the water pressure downstream drops below about 35 psi and shuts the pump back off again when pressure builds back up to around 50 psi.
This setup means every portion of the water system, be it hot or cold, downstream of the pump is under pressure, the SAME pressure created by one single pump.
What you are proposing is to merely add a few more feet of plumbing within that same, equalized pressure system. Without a difference in pressure between the two ends of a tube nothing will flow until you put a pump between those two ends.

JaxDad- I understand what he is saying, but he is suggesting I buy ANOTHER pump to put on my system. Why can't I use the pump I have? In other words, by teeing into the pressure line near the hot tap at my furthest point, the existing pump can do the circulation without adding another pump.
I think 12thgenusa is talking about what I was asking about. Either way, thanks for the input.

Smkettner- I guess that is another option, but I don't have $217 I want to spend on another pump. I think my idea is much easier and cheaper.
