I have a pool that is at least 25 years old and it has a hayward filter and a jacuzzi pump and I was looking on the multiport valve and it doesn't have a rinse setting. I only have Filter-Recirc-Backwash-Winter, it's a 4 way valve. Do I need rinse in order to have better sand cleaning? If so, can I just buy the multiport valve and keep my existing sand filter and just replace the valve portion?
Where would be a good place to purchase one online?
