Thanks. Yes it does look simple, but after further checking on line the head is only $28.+ bucks and the ring $10.95. However, shipping and handling on the head is almost $19 (ridiculous) and $5 on the ring (also high for such a small item that will easily fit in an envelope). Added all together, that $63. If I could find free shipping for about the original price I'd do in a heart beat, but now I need to ponder if I might as well spend the bucks to buy new. Not a lot of places sell the parts for the Hadley pumps.
