plumbing help

just wanted to ask a few questions.

i have got 3 holes drilled in the bottom of my tank....

1- wier drain ( to sump )
2- CL outlet
3- CL return

i have 1"(25mm) bulkheads on each. with 1" ball valves on each.
will ball valves completley cut off the water flow. or do i need to add gate valves ( or sumthing similar ) to prevent any water getting through AT ALL. i cant find any PVC gate valves that are any good ( or below Â£40 a piece ) could i use brass fittings ??

No brass that is a definite no no. Ball valves will shut off fine till they eventually get crusted up with calcium. Gate valves restrict a bit more then ball valves. I use ball valves, they just need to be worked a bit every once in a while.
