Hello there
My daughter just purchased a house and she had a plumber to replace 2 radiators
After bleeding system and radiator fitted, plumber couldn’t find pressure gauge on the system
Here are some photos . Ideal es38 combi

Have another look under the boiler, it may be on the flow pipe (far left)

There is the flow pipe but not pressure gauge

So , shall i remove this elbow valve and replace it with a one with a pressure guage attaced to it " the proper one 175528 ", I double checked and can not trace a pressure guage attached to the system. Do this flow valve comes with a new boiler or purchased separatly?
