Keystoker KA6 Water Pressure ?

jcw265 · Post by **jcw265** » Wed. Sep. 30, 2009 9:24 am

Hi everyone its getting that time again to fire up the KA6 again , I was putting it all together and noticed the pressure guage was showing 25 psi and don't recall having any pressure till its fired up, Also where I live we lost our city water and are now on county water which required the removal of the city meter to a county meter, also we had some sort of meter in the house which the county removed and just hooked the 2 ends together to form a loop. So the questions is 1) should I have pressure in the boiler until its fired up. 2) could the meter replacement cause pressure to be in the system now 3) how do I remove the pressure ?

Just another note when the boiler is running I have never had pressure over 18psi this is why it caught my attention , not to be running and show 25 psi ?? as always thank all of you for your help every year

Love in Christ

Jay

It will be under pressure whether running or not due to the feed water PRV valve if the feed line is open. don't forget that your water supply in the house is under pressure, and that it needs to be reduced to feed the boiler. You can relieve the pressure by opening a drain valve or the pressure safety valve. If the pressure returns to 25# I would think your PRV needs some attention. 25# is pretty high. The meter change should have no impact on the boiler.

drop the pressure until the highest radiator in the house will no longer bleed air or water

THEN -- increase that by 3 pounds

I usually slowly open the pressure release valve to decrease the pressure.

I'd use the boiler drain to relieve that pressure. Too often a pressure relief valve will not properly reseat due to a small amount of sediment and may drip. If your boiler drain leaks afterward, you can at least cap it.
