In my 25 years of experience working with commercial pools all over the country this question has come up many times, sometimes in the form of:
“Do I need to replace all of my equipment in the pump room?” or “Do I need to drain my pool in order to convert to a Salt Pure® system?”
Neither is required.
There are no major alterations or equipment removal in the pump room; all we usually need to do is install 2 pieces of equipment. The Power Supply sits on the wall and a bypass is created after the heater and a certain amount of pool water is routed to the electrolytic cell which is also mounted on the wall and connected to the Power Supply. We usually leave the original Chlorine delivery and pH systems in place. This satisfies the State Health Department, and we can use the pH delivery system, although the Salt Pure® system will consume about 60% less acid or CO2.
Unless the pool needs repairs or renovation that require draining, this too, is not required. We would need to have salt added to bring the level of salt in the water to around 4,000PPM; if the pool has been running on liquid chlorine the salt level in the pool might just need to be “topped off” due to the fact that liquid chlorine contains about 2+ pounds of salt per gallon added. If the pool was on Calcium Hypo chloride it might need a partial drain to bring the calcium level down a little.
With the correct planning before the installation, most installations will take about a day per body of water depending on the complexity of the pump room. Pools can be shut down one day at a time.
Once the equipment is installed, and the correct level of salt is reached, presto you are now manufacturing 100% pure natural chlorine, minus the nasty additives. Stand by and wait for the swimmer compliments…
