Everyone update on the waterpump nipples. I bought this kit off of amazon. It was a little pricey like $60.00 but it’s made in the USA and high quality. They are made of a hardened steel very durable. You drive the correct size down into the pipe fitting make sure to spray the bottom threads with penetrating oil then put a pipe wrench or large adjustable on the top and the pipe fitting twists right out. Really great product. Just though I’d pass it on.
