My main concern was running the heating system with all the new rads , 3 way port and pump without inhibitor .
I have no issues in fitting a filter.
After lurking on this forum for last couple of weeks while i was having bathroom ensuite upgraded . Inhibitor in CH seemed a must i was just thrown by his sudden claim that if he were to add the inhibitor it would cause damage to the boiler with out a filter .
Screwfix did not have filter in stock so plumber has agreed to return to fit filter Saturday .
System has no inhibitor at present ,is a couple of days with out inhibitor ok ?
should i buy a bottle and add ?
