We are renovating the house and redoing all of the plumbing. The city water pressure is 40psi at the meter(3/4" from meter to house) , which city says is acceptable. We used to have 1/2 copper throughout house but we are going to upsize all of the main lines to 3/4" copper and use 1/2" from the main runs to each sink/shower/etc. Hopefully this will help make showers more enjoyable as water output was crappy before.
The main question I have is regarding recirculating the how water. From what I read, there is a strong chance that we will have a significant hot water delay now that most of the lines will be 3/4". We plan on upgrading to tankless water heater in the future, but not for another couple years. Which recirc setup would you guys suggest? Would it be best to run a return line from the furthest sink or are the newer under-sink setups sufficient? I just want to "do it right" the first time and be done with it. What is the "right" way in this situation? IF I do indeed need to run a recirc line from furthest sink to hot water heater, is it safe to assume this can be 1/2" even though the feeds will be 3/4"?
Suggestions?
