I have a Pentair Legend II pool cleaner with a Letro backup valve. I noticed that it was getting stuck on the steps and the backup was not cycling. Dis-assembly of the valve revealed that the gear mechanism inside is stripped and no longer functional. The valve casing appears to be in good condition and I can buy a new gear assembly for around $48 online. Or I can get a whole new valve for just $8 more. None of the local pool stores carry parts for the Letro, but during my search for a new gear assembly at the local stores, one of the sales people told me I should just replace the Letro with a Polaris backup valve, as their design was much better. At the time, I thought he was just trying to make a sale, since Polaris was the only brand the store carried. But before I order a newLetro backup valve, I thought I'd ask here and see if anyone had an opinion as to how the two brands compared to one another. As far as cost goes, there doesn't seem to be much difference between the two brands.
Can I replace my Letro backup valve with a Polaris-made model?
Is the Polaris more reliable than the Letro?
If I go with a Polaris, there are several models....which model should I purchase?
Thanks in advance.
