I have a Hayward Variflo Valve and noticed last night that when I ran the filter, water was leaking out of my backwash line. I then saw that the handle pin had popped out of the handle and was stuck out on one side by about 1/2". I tried getting the pin back in but it did not seem to align with the far side. I did not want to hammer or force it in because I have no idea what I am doing. Suggestions for getting the pin back in place and also is this the likely cause of my leak out the backwash line? TIA!
