Any plumbing experts out there? 
I was cleaning out both my master bathroom faucet aerators, and noticed that each one of them (they're fairly old) contains 3 metal/mesh screens in them (they are all just grouped together - completely identical).. I cleaned them all and put it all back together and its working OK, but I was wondering if there was any reason why each of the 2 faucets have 3 screens in them? Is that necessary (would it lower the water flow?), should I use one (and they just CAME with 3 to give you spares)? Would 3 lower the water flow? Hmm!
Thanks guys.
