pvc stuck together

If there's no pressure build up I suppose it'd be OK, but I would not go that route if you can avoid it. When it does fail it'll happen at the worst possible time.
 
PVC pipe fittings have a very slight taper on the inside. This is to ensure a true fit when the glue goes on. if you have twisted the fittings when dry fitting them what has happened is there has been enough friction to ever so slightly melt or fuse the fitting to the pipe. This is a common mistake made when trial fitting plumbing layouts. Try taking a drift of some kind {hardwood or brass, steel if you have to] and place the end of the drift against the end of the fitting and give the drift a good stout hit with a hammer. Try and shock the melt apart. You cant leave it as it is because it will leak like a sieve and eventually fail completely.
FYI the glue is actually a solvent. it dissolves small thickness of both the fitting and the tube and when the solvent evaporates off the melted PVC surfaces combine as one. You can recover fittings by cutting them off the tube and spread some solvent glue on the inside and set it alight with a cigarette lighter. Give it a minute and the tube remnant will soften to the point where you can grip it with long nose pliers and twist it out of the fitting. ensure that the flame is extinguished of course and be careful everything will be HOT!!!
 
I know I'm late to this party and am sure it's fixed by now but for in the future......Use a crescent wrench (I use knipex pliers) sized to the pipe and give the fitting a couple firm whacks. It'll slide right off. Also ream the outside of the pipe.....If you don't you're more likely to scrape the glue off when assembly.
