Need helping figuring out my equipment. We just bought a new house with a pool and after all my research can't seem to figure out how my system works. It is pretty old (house was built in the late 60's which I am pretty sure was when the pool was built as well) and currently has a sand filter.
I have everything working pretty well but cannot seem to figure out where the multiport valve is in order to set the system to backwash or waste. The only valve on it at all looks like this:
I will try to get actual pictures of the filter system included as well but for now this is all i have. This is a bad picture of it but the handle says "flow" with an arrow which is why I thought maybe this was the right valve. The brand on the valve is Ortega which so far hasn't helped with my research.
I have turned it both ways however and it does not appear to change the way the filter runs.
Like I said before everything seems to be running fine, I would just like to know that I could set my pool to backwash or waste if needed!
Thank you and I am sorry if this is not enough information to get an answer. Again I will try to get pictures up later tonight or tomorrow.
