Can anyone tell me where I can purchase the o-rings that came with the IC-40? I have managed to break both of them. I have been looking all over the internet but with no luck. I have called pentair and they can not tell me the size as they say "we will not give out that information".
I have found that they come in a packet of 10 part #521147 but I can not find any one who sells these.
