I'm nearing completion of a rehab of a long neglected pool (came w/ the new home). I cannot know the exact age of the pool, but I would guess about 25 yrs. Job started with replacement of all mechanicals on the pad, and thanks to mission creep has included resurrecting the floor cleaning system. As the subject line indicates it's a Pool Valet infloor system that was painted over some time ago.
Much drilling, chiseling and cursing later, the old floor nozzles were removed with minimal damage to the cups in the floor, lines back to the valve cleaned, and new nozzles installed.
My question is this: How does one decide to drill, or not drill the optional holes provided in the new nozzles? All the new nozzles are supplied drilled on one side and also have blind holes on the opposite side. Drill or no? What decides?
Thanks for any ideas. Pete
