water will not come on in faucets, it was running just a few minutes ago now nothing, checked and no burst pipes. Could a pipe be frozen? we have had below freezing temps for days.


yes probably...one thing to do is to remove the aerator's
from them open them up and see what happens. don't close them cuz if it's warming up we hope... it'll help them flow better to get the water moving thru the pipes.
if it is just one open the vanity doors, or any doors that contain the fixture plumbing. let some heat get in there.
is water ok running in other areas? or whole house?

I do not have a mixing valve on my boiler, will this create mixing problems? Sometimes it mixes ok. other times it is all hot or cold. I replaced the cartridge once. This system is only a couple of months old.


If your posi-temp valve is working correctly this should not be a problem. Does your hot water temp. ever get extremly hot or just warmer? The way the posi-temp cartridge is designed if you have a large drop jn cold water pressure then the inside piston is supposed to slide to the hot side restricting the flow of hot water to a safe level.If the pressure on the hot side drops suddenly then the valve is supposed to restrict cold water flow.
If the temperature gets to a unsafe level you can adjust maximum hot setting by removing the handle. There is a allen head set screw on the bottom of the handle. Loosen screw and pull handle off. On the newer models pull off chrome sleeve from around valve body and slide outer geared disc off enough to seperate from inner gear. There are markings on disc with arrow pointing to h. or c. Adjust outer disc in the direction you want to adjust and slide it back so that gears engage. Each tooth on gears will change water temp. about2-3 degrees.Try it and readjust till you get the hot set point you want. One other thing you could do is install a small pressure tank on cold water line to compensate for pressure changes. Hope yhis helps you. Thanks
