That's all good Willie, all things we offer to do as dealers but extremely rarely does the customer want to pay for thr extra plumbing, I always isolate the pumps though.
Installing your own as a DIY project and understanding thesystem is far different from a job out in thr field, there your under time constraints and working for someone else under a tight budget lol.
Today was an example, had a guy come by who was gonna run multiple loops off of one pump, no zone valves, just t's, he couldn't understand why he needed to isolate the pump or do anything correctly, he was like, "you mean to tell me you don't think water will flow through a t". I gave up, took his money and went on about my day... What can you do when the guy who is asking you questions already has all the answers
