So I want a FlowVis to know what my flow is - I've read great things about them. Over the course of the winter, I ordered a Jandy retrofit only to figure out later that the PB had used a Pentair check valve (and there's no Pentair retro-fit from FlowVis - the top of the Pentair is bigger, and has a square flapper - they started going down the path of engineering a retro and then aborted due to complications).
What I have won't work, so I have two options, both of which require me buying a new FlowVis check valve:
1.) cut out the current check valve, and try to somehow make a new one fit without re-working all of the plumbing between the heater and the SWG
2.) add a second check valve somewhere
If I go with #1, any suggestions on how I can do this without having to re-plumb everything?
If I go with #2, are there drawbacks to having two check valves (I'm assuming that the flapper has some negative effect on flow, so by having two, I'm multiplying the effect?
Any other suggestions?
Here's what my equipment looks like today:
