I have an 80,000 litre (21000 gallon) pool which is almost 30 years old. The system runs with 1.5 inch "IPEX" pipes (I believe these are PVC but am not sure). I am looking to convert to a SWG, but it seems that the IC40 unit I am looking at connects to 2 inch "PVC" pipes. What are my options ?
Second question - the previous owner of this house told me the pool is 80000 litres (approx. 21000 gallons). It seems that 20,000 gallon is a standard size, so I'm wondering if the previous owner simply rounded up to 80,000 litres when in fact the pool really is 20,000 gallon. SO, the questions is. do I need the IC40 unit or would the IC20 unit be large enough for my pool ?
