I'm a novice at this stuff. I soldered the male side of a 1/2 inch "street 90" connection into the 1/2 inch female opening of a washing machine valve. Just after I'd finished and it had just begun to cool I noticed its position wasn't quite what I'd had in mind. So I reheated it a little and twisted it (about 5 degrees) to the position I wanted. Is there a problem in doing that? Thanks for any advice.
