Just had my DE filter replaced with a cartridge filter. The pipes going to the motor have three valves. Since the replacement I am losing water and can't remember which of the valves should be open and which should be closed. I believe one is for the vacuum system which I don't need, one is for the skimmer, and one for the main drain (can't remember which is which though). The two valves on the right regulate whether I am using the returns or the in-ground cleaning system. I have no problem with that.

  • Where do the two pipes on the right go?

  • Hi @user21223! It looks like you’ve accidentally created a couple of accounts. If you’d like to merge them (there are some advantages to doing so), the instructions are here. Welcome to the site!

Losing water? As in your water level is going down? That is not a problem with valve position. You've got a leak somewhere and a professional needs to address that.
