4" arg keep priming

hi been out fist time 4" agr
keep getting a lot off priming help
is there any think i can add to water to stop this

Best thing is just keep washing it out, if its a brand new boiler then it will take a few steamings and washing outs for it to clear.

Just keep boiling it up and then draining down (once the fires out and pressures down of course)

Try keeping the water level between 1/4 and 1/2 gauge.

Hi Richard

How much boiler treatment are you using, if you put too much in it will cause the engine to prime.

Many thanks

2rd steaming so kept water level down raised steam 1 3/4 2 hours done 3 miles straight off only stopping to refill oil and cold water stop for dinner then done the same got some steep hill round me i had no issues with priming keep it in steam at 100 to 115 only had safety go off 3 or 4 times it pull and run so well
so thanks for the help yes i had to much water in and may be to much treatment in
thanks richard

On a new boiler I was told to steam it for a couple of months, regularity washing out with clean water to get a layer of rust inside the boiler as then when treatment is added it's got something to cling to. Sounded plausible so that's what I have always done. My 15 year old Aggi is still clean inside with very little rust as every couple of years I put the camera inside to have a look. I also never put water in the boiler I wouldn't drink!! we have quite soft water in Cornwall.
