Here's a question I have from my one pool store visit last fall. They told me that I should only rotate the selector handle on the Sand Dollar multiport valve in one direction (I forget which) or it would tear up the spider gasket in the valve. Specifically this is a Pentair #262506 valve. I replaced the valve and took the old valve apart. I couldnt see that one direction over the other would really make any difference. I've searched on the internet and the only precaution I found was to shut off the pump before changing valve positions. Was this more pool store made up stuff?
Thanks,
Russ
