I am a plumbing contractor in tampa. fl. I finished a house 6 months ago. The homeowner had culligan install a water softener when she moved in. This is a large house and I have installed a hot water recirculation system. I have been out 5 times to rebuild the pump which keeps the hot water recirculating. Each time there is green sludge in the pump. I have installed a basic filter inline before the pump and in a month's time it fills with this sludge and still gets through and damgages the pump. Now I have done 25 or more houses in this area with recirc systems in them and have never had a problem. The culligan rep told me this is caused by the polyphosphates in the water?? A couple of other people have mentioned a possible algae bloom in the water system of this house?? I believe this is a water softener problem only because of the track record of all the houses I have done with no problem. Last year I was called out to a house with a similar problem. The homeowner had a Kinetico system installed 1 1/2 years after they moved in and within 2 months they had this green slime. I rebuilt the pump twice for them over the period of 4 months and installed a filter and never heard another word from them. Any suggestions/help would be greatly appreciated. Wayne
