I hope this post meets the posting requirements.I have a new house and the hot and cold were switched in my tub. It was a delta single handle system. I watched a youtube video, disassembled it, flipped the cartridge, and put it back together.The repair initially worked. The hot and cold were on the correct side and the faucet worked properly. However, after an hour the faucet started to leak. Like a big leak.I went back in and re-seated the little gaskets and springs and tightened everything back up. As far as I know everything was assembled in proper order. Unfortunately, after 20 minutes the leak restarted.I watched several additional videos about fixing the leak and read a few websites, but nothing has helped so far.Do I need to replace the gaskets or silicon grease them? I tried finding a repair manual for my faucet without success.http://bit.ly/2GCXjD7 via /r/DIY http://bit.ly/2CsEnTw
