Thanks for the feedback folks. To clarify, I have always used a pressure regulator between the outside faucet and the incoming hose. My pressure measures 45 PSI before the regulator. The old regulator was rated 40-45 PSI. I can't see how one of these could go bad. There are no moving parts. I changed out to a new one just to be safe. They are pretty cheap. I suspect a possible line surge may have overwhelmed the regulator. I do have a quality filter that I used in the summer, but it will not fit under the sink.
You didn't give a model number but I am betting the one that is blowing up looks like
THIS ONEWhich is a cheaply made one time use filter for $16, you HAVE to replace the entire filter every 90 days and if you are not using it it is impossible to really safely "store" it (IE you can not dry it out to store which can allow unwanted bacteria/mold to grow inside the filter)...
I am thinking that with a little creativity on your part you WOULD be able to "find" a place under your sink or even nearby to install a filter like I linked in my previous post...
Right now, you ARE buying a cheapo ONE TIME USE filter, it is not designed nor intended to be permanently installed and left there forever.. The results of such a cheap filter IS the possibility of breakage..
