I have a pretty large pool that was built in 2000, originally with 1.5 inch pipe. When I resurfaced the pool in 2011, among other things, I replaced all of the 1.5 inch plumbing with 2 inch. All new piping was installed from the skimmers and returns to the equipment pad, and all piping at the equipment pad was replaced with two inch (including at the pump fittings etc).
Having said that, I just noticed (while installing a manual heater bypass) that one of my Jandy valves was never upgraded. Instead of replacing the valve with larger diameter flow, the installer just RE-used the existing 1.5-2” valve (putting the 2 inch pipe on the outside of the valve on all sides - see photo). Will this have a significant impact to flow? Worth changing while I am doing other work?
The valve splits the returns between my 5 eyeball returns and my waterfall (really just water return flowing down a rock). I have a Jandy actuator that either cuts off the waterfall or splits flow between waterfall and returns. I suppose the returns and waterfall might be stronger with less flow restriction - but not sure of magnitude.
