Question about Watts 0274193 N170M2 3/4"
OK, without model number and pictures/more description, you need to make sure the the filler valve is properly adjusted. This valve will normally be on a copper pipe leading into the boiler. IT will have a collar/handle that you can raise/lower to open/close the valve. It will also have a screw to adjust pressure. If you open it and hold it open (usually up) the system should pressurize to the pressure of your incoming plumbing (should be ~40PSI). If you close it and the pressure drops below 6 try the screw. If this does not solve the problem you may need a new intake valve.
