OK pump guru’s, here’s one for ya.
System was installed several years ago during the home construction with the previous owner. He moved onto another maintenance guy, who installed another tank after the first one “popped”, and when they installed the new tank, they removed the chiller from the system. (Don’t ask why, I don’t know the answer).
The system runs 80-81 on an almost constant basis, deal with several issue caused by the temps, so I want to put a chiller back on the system. (I have already checked all sources for heat generation, etc etc).
Anyways, the original installer had the bright idea to run 1” pipes the way you see them in the diagram, outside to the chiller. Chiller outside, great idea, pipes ran the way they are…, in the walls… crack cocaine? Shrooms? It was during construction, they could have easily been run low in the walls…
The system has 2, Current DC return pumps, but will not push the head pressure that is present with the plumbing the original installer installed. Being I have several pumps laying around, I have tried Mag drives up to a 24, other AC and DC pumps and the latest attempt was with a Jebao DCP-18000 (I have this for moving SW from my mixing Tank).
I can get water to, and through the chiller, but it cannot make the push back up. There are no blockages as I can push water through each pipe without issue
FWIW: I believe there are a total of 10, 90’ elbows (just assuming since I cannot access any of the plumbing except the ends of the pipes where they terminate), 2 ball valves at the chiller (Just installed them where the pipes were capped outside the home).
My thought is that I am going to have to go with a Reeflo pump with the capability of overcoming an incredibly high head pressure.
Open to suggestions, I just don’t want to drop hundreds on a solution hoping it works.
