Periodically I've seen people mention those "flying saucer" looking diverter valves for the bottom of the skimmer. I have two questions about those please.
1) Where to buy? I look online but never seem to find something that looks like the pics here.
2) Do I understand correctly about these valves? If I have one of these and my skimmer basket gets stopped up (tree leaves, etc.), the diverter will open the main drain, thereby preventing pump damage due to the clogged basket, correct?
I'm asking now as the trees have been at war with me for the past 6 weeks. I'm afraid the basket is going to plug completely up one day while everyone is gone from the house.
