"The product itself seems well made, however it does not match the photo.
I needed to replace a faulty PRV and the picture matched exactly the layout I needed, but the control knob is opposite the Pressure vessel connector, not opposite the gauge connector, so I needed to to adjust the pipework to match."
"Not impressed with this product. The sketches are all back to front Connections to the heating system are not explained. The pressure gauge does not have a RED system pressure pointer. And worst of all the the gauge reads upto 10Bar so is hopeless for reading typical system pressures of 1.5Bar.
