probs with 32 degrees slide check

i apologise if this has been answered already but i don't have time to do a search.  i recently bought a 32 degrees remote with a slide check.  worked great for an hour then started leaking from the slide check.  no matter what i did, it wouldn't stop.  took it back to the store and got another one.  2 hours into using the new remote, the same thing happened.  have there been a lot of problems with these?  is there a way to easily fix it because i can't seem to find the receipt.
