ok, I have been through 3 pressure gauges.  every year I freeze the gauge and break it.  does anybody have any good ideas on what I can do to get all the water out of the gauge?  I was thinking about puting in a small drain valve from an aquarium behind the gauge to drain the water out. but I don't know if it will work or not. any ideas?

Dang, never thought of that one. Haven't ever froze mine up, but I don't believe it reads very accurately either. Might be hard to get the air back out of it in the spring if you bled it. You'd have to bleed it again in the spring under pressure to get the air out so it would read correctly again.

Never even thought of that as being the reason mine does not work.Makes perfect sense though....

I have ruined three of them. maybe I should just start taking it out of the dash and keeping it inside the house for the winter. my luck I would forget were it is and still have to buy a new one.

In a conveint under dash location cut the hose and install a brass conector. when cold winter comes just undo the fitting and let the hose from the H2O gauge hand down for the winter. You can get small plastic conectors for windshield wsher tube. I just use a small zip tie as a hose clamp and even with 35+ lbs of preasure I have no problems.

Another idea would be install a small tee and a valve off the tee that could be opened during the winter. We have instrument type 1/4 and 1/8 inch tubing tees and valves at the plant that would be ideal for that. But I'm not sure where they could be purchased at a retail store. Maybe Lowes in the plumbing supplies for something like fitting up an icemaker or something similar.
