leaking from pressure relief pipe

[felts28]

i have a potterton 80e boiler.
i noticed today that the pressure had gone down a bit (it had gone down to 1bar)
i put the heating on and put a little pot under the pr pipe outside.
water had dripped out (something like 50ml - 75ml)
the pressure relief gauge had only risen to a little (less than 2 bar)
help

If your pressure gauge only reads two, then it's probably one of two things:
damaged PRV (pressure relief valve) opening too early. should open a 3bar.
or a blocked presure gauge and the actual pressure is in excess of 3bar.

is it still dripping or has it stopped? what is the current pressure?

i checked the pipe outside about 2 hours after turning the heating on.that when i see that it had dripped.
after emptying the pot it doesn't seem to have dripped anymore water since.
the gauge reads roughly 1 1/2 bar

1.5 is a good level.
maybe you put a bit too much pressure in initially. Keep an eye on the relief pipe for more drips. you may need a replacement prv. easy on that model boiler.

since i turned the heating off last night, the the pressure gauge now reads 1 bar so the pressure has gone down a little.
i pretty sure the pipe has not dripped anything since.

i'll have to see what happens when i turn the heating on later
