Boiler pressure

[Lizzy Holmes]

My son has changed a radiator for me changing the pipe to 8mm so that it could come through the wall instead of up from the floor. Had no problem with the first one he did but since changing the second the boiler pressure keeps rising. Could anyone tell me what could be wrong he has used the 15 - 8mm reducers and elbows.

The filling loop is possibly letting by or has been left slightly open.Have a look at that

Hello what he did should not cause a problem but if you have a combi and the top up has been left slightly open then you would have this fault. If it is a combi and on a flexi filling loop just close the inlet fully disconnect it and it should resolve the issue.

I would think you've got a combi and he's left the filling loop slightly open. Check the silver loop under the boiler.

I have some good advise............get a plumber to do the job. Now you will probably need a new boiler PRV and you will need a gas safe engineer to fit that.

thanks for getting back to me - have tried the inlet - think its ok but haven't got the guts to try to disconnect it (son doesn't live with us)so will have to get help tomorrow!
