What you need is a 1/2" NPT 3-way valve. Search that on Amazon or google. Looks like 30 bucks for a competent one. Here's an example: Industrial Grade 1PZA1 Three Way Ball Valve, 1/2 In NPT, Brass: Amazon.com: Industrial & Scientific |
We get guys doing that up here and they are also the guys coming in to get their heater core flushed every winter because the lack of flow forms a sludge and makes it work poorly just my .02
