Had an issue where the pipe nipple used for the ball valve was a tad loose in the hole that was drilled for it and it would just get worse over time due to opening and closing the ball valve, so I ran to the Depot and snagged up a couple things and fixed it. Now it is snug as can be and isnt going anywhere. Here is what I did:
I got a cheap 3/4 x 1 1/2" pipe nipple (3/4 x 1" would have been better):
I also went to my local Fastenal and got a pack of 1" stainless steel washers and attached them as you can see below. It is really tight now and won't budge, so mission accomplished.
Just wanted to pass it on as this is better than a weld to me since it will never budge and is completely removable with two pipe wrenches.
You can also buy a 3/4" pipe bushing and put it on the inside with 2-3 washers and tighten the ball valve on the outside. This method will probably be cheaper due to the less fitting and washers needed.
