So if that cartridge snaps when removing? Can you open the the flow nut on the bottom to help take out the rest of old cartridge?
@@Razz60 Yes you can remove the whole block and try to remove the cartridge. Many engineers would just change the block instead of changing the cartridge.
@@MHKBuildingSolutions ok i see so its good to mention to customer theres a possibility could snap an whole block may need replacing
@@Razz60 Yes it's always good to leave a caveat as anything could happen.
Which part of the cartridge needs silicone grease? The rubber o-rings definitely but is it worth greasing anywhere else?
Just grease the o rings.
@ Thank you
You didn't drain the expansion vessel?
@@oldguy8078 It was drained when the boiler drained mate.
