8mm or 10mm from regulator

[Neil n Pat]

Does anyone know whether the pipework from the regulator is 8mm or 10mm on a 2009 Knaus TI
Checking the diameter of pipe at the boiler, fridge etc doesn´t reveal the true story as the 8mm may go into a manifold somewhere with 8mm on the input side and 10mm on the output side.
From the photograph it is impossible to determine the size as the rubber sealing ring on the pipework from the regulator cannot be pealed back to reveal the pipe.
Why do I want to change the regulator you ask ? The Truma boiler requires 30 mbar which without will activate the dreaded red LED flashing. Not sure how critical this is or indeed what drop in millibars will activate the red LED.

Our replacement Truma crash safe regulator came with a 10 mm attached and an 8 mm reducing olive?

Often 10mm to manifold, then all pipes 8mm from that go appliances. But only way to know is measure it.

Normally a 17mm nut on 8mm and 19 mm on 10 mm .
Can’t you get to the pipe somewhere ?

I can get to the boiler, fridge and cooker pipework but for the life of me not the regulator to the manifold. I can measure the nut on the regulator though having a vernier caliper. Thankyou for the input.

The nut on the regulator should give you the size
