My Hayward pump is leaking at the shaft stem. I am guessing it is the seals. When I replace them on Hayward's site they say :
Clean and lubricate the impeller hub shaft and pump housing seal recess with a dilute solution of non-granulated liquid-type soap. The use of petroleum or silicone lubricants can contribute to seal leakage.
But other places on the web I they suggest to lube with silicone.
Which is correct? And if soap is the answer -- how 'dilute' should it be?
