If it leaks again, you could use electrical pvc parts to fix it. Since their
threads don't taper like irrigation pvc parts, they could be tighten all the
way. The spigot I made doesn't need gasket nor sealant.

I just had the same "great idea" and have a spigot made from PVC fixtures at
the bottom of my new skippy filter. I had a tough time sealing it and am
now wishing i hadn't cut that hole! I think I have it pretty water tight
with a rubber ring and plenty of silicone for good measure. If it
eventually leaks it will be a slow one. I'll start it up this weekend and
see how it holds. The tub was about 20 bucks so I won't be out a ton of
money just alot of time and effort.
