Definitely a gate valve. You need the multiple turns to be able to fine tune the flow. You can get them on Amazon, good prices too http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias=aps&field-keywords=pvc+gate+valve&x=0&y=0creepyoldguy;5141980;5141980 said:1.). Ball or gate valve? I assume gate, but I'm having trouble locating a PVC gate valve
2.). Placement of valve? Due to the short stand, I had 90 almost instantly from the bulkhead, thus, placing the valve past the 90. Is this an issue?
