The CompuPool Pool Salt System Chlorine Generator 40K gal is on the way. $649 with "Buy it Now" on EBay.
I plan to DIY. I am a handy guy but welcome all comments and suggestions!
As I inspect the existing plumbing it is really old an seems to have numerous repairs.
It also uses 2 inch PVC which I understand is small for a 27000 gal pool by today's standards.
The heater doesn't work and I do not expect that I will be heating the pool with natural gas in this lifetime.
So ... should I take this opportunity to replace all the PVC?
I was thinking of using 2 inch input 2.5 inch output 3-way valves and plumb with 2.5 inch PVC on the filter/pump side to avoid restricting 2 inch x two pipes to 2 inch x one pipe. That way I will at least maintain a larger cross section in the system.
I'm also thinking I should ditch the heater in the circuit.
If I switch the valve at the filter too (as I must) that will be a significant expense just to get a 2.5 inch cross section. Is that worthwhile overall?
