I have been browsing the site and have seen many setups with a typical water spigot plumbed into the PVC after the pump. My old house even had one that I never used. My current older new-to-me house does not have one. But, since I am envisioning redoing the entire pad to fix some plumbing issues, add equipment, etc, I figured I would ask:
What is it for? Is it needed?
My only guess is to take a water sample ... but that is easy enough to get from the pool right?
