I have a Hayward DE6000 filter with a Hayward Selecta-Flo Valve SP740DE. My problem is that the lock nuts connecting the two have cracked. Due to the flair union on the pipes coming out of the Selecta-Flo am unable to put a new one on. Is there a way around this without having to replace the entire Selecta-Flo Valve? Severall of my local pool stores have told me that is the only way to solve this problem.
Any help on this issue would be appreciate. I have found "split nut" but they are threaded for the booster pump and not the filter.
