    Hi All,

    My central heating system had a tap, so when the pressure went low in the system you could open the tap to top it up from the water mains.

    Few years ago a plumber installed an automatic pressure regulator thing (i think i have attached a photo).

    The pressure has gone very low and this thing does not seem to be working. I have tried screwing in/out the threaded bit, to no avail.

    Does anyone know what it is? is there a reset thing on it? Is it handy to replace if its borken? etc
    Thanks
    Roytheboyo

    They'll only hide a leak. Should be replaced with a filling loop

    And the cause of the pressure loss investigated and repaired.

    Thanks for replies. I will look into replacing it. The pressure always needed topping up 1 or 2 times per year, its in an estate and neighbours so the same. Is it definately leaking?
    Anyone know how to fix the pressure top up yoke?

    Check red pressure vessel / tank is light and hollow sound when you tap it with a spanner. If solid and heavy call service eng / plumber.

    Plastic handle on valve is on/off like a tap. Anty clockwise on/clockwise off.

    Tredded part is to ajust for proper pressure, screw in for higher p. Out for lower set at 1- 1,25 bar max and then turn off plastic tap. If not ok call plumber and also get him/her to add licquid leak sealer to system. Plumbers are there for a reason, to be called.
