After I replaced the tee fitting connected to the downspout and sump outlet the other month I thought I learned my lesson in making multiple trips to hardware stores by buying multiple parts and returning them later.
But Today I learned that even if I plan ahead it really does help if I buy the correct part too.
A week and a half ago I bought a couple of outdoor faucet fixtures. It rained last week so I am getting to it now on a beautiful Spring day, not a cloud in the sky. But of course the anti-siphon fixtures are meant to include the entire sillcock unlike the faucet fixtures.
So back to the hardware store to return both, buy groceries, go back home, take measurements on the inside, go to a different store (big box one unfortunately), and got to work.
A bit of wrenching later and cursing the new part for having smaller openings in its face plate. No leaks inside and outside! 💪
