We've been homeowners for 40+ years and home builders for 25+ years and this is the biggest hunk of karp we have ever purchased. Within 40 days, every joint is leaking, there has never been any pressure in the spray attachment. The unit sounds like it's strangling. I took the filters off the main piece and there was a disc with a tiny hole, that I took out, and got a little better pressure from the main faucet, but the spray arm remains just a trickle and we have to keep towels wrapped around it until we can purchase a new faucet. Buyer beware.
