I decided to replace the 20+ year old gear in my pool shed. Just purchased a Pentair Intelliflo VS Pump, Clean n Clear Plus 320 sq ft filter and an EasyTouch 4P control panel & wireless network adapter. I also bought a FloVis Flow Meter.
I will have an electrician do the line voltage wiring, but I will do the low voltage and plumbing myself. I had a couple of questions.
1) I've seen the term 'vacuum to waste' which is something I don't currently have. I'm not totally sure how to implement one, but was wondering if it's as simple as putting a Jandy 3-way valve after my pump and before my filter? So when I want to vacuum to waste I just turn the valve and send the water to my garden? Or is there more to it than that? (Or do I really even need one?)
2) I'm assuming I should install the Flovis Flow Meter after the filter, before the Pool inlet?
3) So the Flovis Flow Meter will show me the GPM for whatever pump speed I use. Do I also need to put pressure/vacuum gauges on either side of the pump as well? Is the only purpose of measuringTotal Head for computing GPM, or are there other good reasons to monitor this? If so, can anyone recommend a set of pressure/vacuum gauges and tell me where I should install them? Do they go on the pump drains directly? Or should I put in the PVC piping close to either side of the pump?
4) I am thinking about adding some automated liquid chlorine dispenser (later -- I haven't picked a solution yet). Since the Flovis is also a check valve, could I put the liquid chlorine injector after the Flovis, just before the Pool inlet?
Thanks -- what a wonderful resource this is.
P.S. The solar part of my plumbing is rather mysterious, so I'll put that in a separate post...
