    Pentair rainbow #300 Off line chlorinator check valve

    I use an offline chlorinator when I'm away. I recently installes a pentait rainbow #300 off line chlorinator. The fine print suggest installing an "optional" 1/4 inch inflow check valve #R172323. I already have another 1 1/2 inch check valve after at the heater outlet. When I spoke with teh Pentair tech support they basically explained that it is really a "must have" to protect pump and other equipment. Just wanted to let folks know.

    I suggested to the rep that if this is the case they should include it.

    Anyone have any thoughts?

    Thanks.

    Yeah, but if they included it they wouldn't get to charge you extra for it and they wouldn't get to charge you a service call to tell you that you should have installed it in the first place.
