Hey everyone.
I'm new here and have been looking around the forum for this specific question. I have seen a few threads that seem to discuss the same question but I had a little more specific question so thought I would ask here.
We are in the process of having our pool built ( just filled a few days ago )
My PB was working on the filter / heat pump yesterday when he noticed the filter PSI was high when running the VS pump. He said he normally sees the PSI around 10 or 12 and it was running at about 20 at a low speed.
He said the high pressure was making it so the return flow was low, and unable to properly circulate. His feeling was that, the water coming out of the filter was more then the heat pump could handle (Rheem 140 BTU 450TI-E) and he probably needed to install a bypass value to level that out.
Now, I have read here and online that having a bypass value is not uncommon, however, when reading about it, its typically around bypassing it entirely, for cleaning or repairs etc. Not in terms of pressure reduction.
My question is, is this type of setup common / recommended, where a bypass value is installed and maybe left a 1/3 open to relive the filter pressure? My first though, was that it would be mixing cold water with warm, and slowing the heating process down. However, its a closed system, so it will eventually be mixing warmer and warmer water as it goes, so I don't know if it make too big a difference. I also saw a youtube video where they talked about this a little, and one guy mentioned that it can help slow down the water passing through the heater, making it heat up more.
I hope I explained that well enough, just trying to see if what my PB is purposing (adding a bypass value from filter to return to lower pressure ) is the right way to go about it, or is there an issue somewhere else?
Thanks everyone!
