per4mer Posted June 7, 2012 Report Share Posted June 7, 2012 So he installed my chlorine generator but the flow switch is directly downstream of a 90 degree elbow! The manual, which he obviously ignored, states, "Important - There must be at least 12 inches of straight pipe run before (upstream) the flow switch. Why is this directive important? How will it impact performance if I leave it as-is? I don't want to make him buy a new part (the existing T is glued) and modify the plumbing if it's not really necessary. Thanks.

Dr. Spa Posted June 7, 2012 Report Share Posted June 7, 2012 Directly after a 90 is excessive turbulane. TO HELL WITH THE MANUAL. You don't think the MANUFACTUERE has any idea what their doing, do you? Quote Link to comment Share on other sites More sharing options...
per4mer Posted June 7, 2012 Author Report Share Posted June 7, 2012 Sorry, I'm not sure I can distinguish between the advice and the sarcasm here. You're saying that the 90 degree elbow will induce turbulance. This turbulance will do what - cause the flow switch to chatter and interrupt the continuous function of the generator which would be detrimental to the efficiciency of the system? I wanted to add the salt and start up the SwimPure Plus as soon as my electrician does his work tomorrow. Can I start up as-is or must I get the installer back to correct the flow switch before? I'm only asking as a concerned owner who bothered to read both the use and installation sections of the manual after my installer was done.

waterbear Posted June 8, 2012 Report Share Posted June 8, 2012 It's the installer's mistake. Have him get a new flow switch if needed and fix it. leaving it as it is can cause problems with your Hayward SWCG.. If you could post a photo of how it is currently plumbed perhaps I could make a suggestion. If there is enough pipe on either side of the current flow switch to cut out and glue into new pvc couples you might be able to reuse the current flow switch.

Pool Clown Posted June 8, 2012 Report Share Posted June 8, 2012 Does the flow switch close when the pump is on? The reason the manual says that is to insure that the flow switch will prove when there is flow. Quote Link to comment Share on other sites More sharing options...
