    I have a leak, a bad one, but it seems to be coming from pretty much everywhere at once on the reservoir..I found the breather clogged solid. When I unscrew it, there's pressurized air in the reservior...
    Will this cause a leak somewhere? I can not seem to locate the source, for the dammn life of me...uses a quart every 3 hours or so.
    I have the breather sitting on a shelf above the wood stove now..
    FISHER. got your ears on?

    If the breather is clogged it will cause added pressure to the system.

    Well your supposta have approx 5psi in the system. Clean it off and operate the plow see where the drips ate coming from

    The grey duckbill breathers are designed to hold 6psi of pressure against the system to keep water at bay due to low friction cylinders. If you're clogged it's going to put addition pressure in the system and it has to release somewhere.

    Did you fix the seal for the reservoir? I would also check the fitting on the side you hit the object, may have damaged the o rings. Remember these only get snugged too tight and they will leak.

    OK.

    Well, the breather was froze up or something, as I could not blow air through it with my mouth, and I have substantial hot air reserves...
    I left it on the shelf above the wood stove, and now I can easily blow air through.

    Also, after wiping off the valve blocks, and having the wife use the left-right control while I watched, I found a "plug" that was loose, allowing the fluid to squirt out like the dickens. Had the o-ring dislodged a bit it was so loose.
    That was a 7 second fix with the allen head wrench.

    All is well again.

    Thanks guys.

    You shouldn't be able to blow through the cap. Might want to get one just for grins

    It's not wide open, it takes the 5psi someone said they hold.

    If you operate the plow and then remove the fill plug or breather there will be pressure, in fact if you take the fill plug off to quick you might end up with fluid all over you, hAve to unscrew slow to let pressure out slow.

    The average people can only blow 2-3psi. Those that are trained or blow things on a regular basis can provide more. The same will also have a higher suction rate.

    I would suggest buying a new vent and try, I'm sure your test will the in the same results.
