Discuss Pressure drop after cleaning filter in the Plumbing Jobs | The Job-board area at PlumbersForums.net
Repressurise you system to 1.5 bar when cold....no more. Well done for cleaning out the filter most people dont bother and block their boiler upI cleaned out the magnetic filter on my Worcester boiler for the first time and the pressure has dropped from about 1.7 bar to 1 bar. What could the reason be?
If you fill to 1.5 bar when cold when the heating circuit heats up it will be sitting around 2 bar, uneccsssary strain on all Pipework and joints. Better to fill to 1 bar so it’s around 1.5 when hot.
I can see where your coming from but if your sealed system can't take 2 bar when hot, I'd suggest leaving a umbrella for when the diaphragm eventually perishes inside the expansion vessel[/QUOTL
Lool I’m not saying the system couldnt handle it , I’m saying why put excess pressure in the system when it’s not needed ?
Also like i said if you pressure to 1.5 bar and it gets to 2 bar when hot and over the year between services if the pressure in the expansion tank was to drop it will raise above two bar. Many engineers don’t check the level of pressure in the expansion tank when servicing.
1.5 bar from cold , why ???????? When any boiler works on 1 .
