I have just purchased a house with a pool, and am a first time pool owner. Pool details are in my sig. I assume the pool was built in 1979 with the house, but at any rate it has, as far as I can tell 1.5" piping for most of the way.
I have purchased some new equipment to refresh my equipment pad, and I will be adding a SWG, VS pump, a Flow-Vis flow meter, and a 520 sqft catridge filter. All of the equipment comes with 2" ports. I thought it would be easier to just cut the old 1.5" pipes off at the ground, then step up with a bushing to 2" and do all the above ground piping with the 2", so I don't have to install reducers at every equipment point. Plus it appears there have been several repairs over the years, and I don't like all the elbows and couplers, and piping paths.
If I am understanding the sticked post "Hydraulics 101... have you lost your head" at worst, this will be a non issue; and at best it will be a minute improvement due to lower head. Is this true?
For reference, I have included a pic of my existing pool equipment "pad"
