Hello..just joined TFP. such a great site I no doubt will use very often. I have a PVC pipe sticking out of the ground about 6 inches high, half way between the two returns, and I'm not sure what it would be for. My steps have jets and a valve to unscrew to let air it for spa like air bubbles.
This pool is an L shape. I bought this home in 2007 and the pool is around 15yrs old and in good shape. I live in Ontario Canada and will be adding some RV antifreeze into the returns and not sure if I could add it through this pipe.
vinyl pool liner and volume aprox 90,000 ltrs. If anyone could help me on this one it would be you guys....Thanks
