    Potable expansion vessel no pressure

    There is not much to see on photos. The vessel is intakt. No leak from the flange or from the valve when it is pressed.

    Potable expansion vessel no pressure

    We have a copper hot water tank with an expansion vessel. The tank is limited to 2bar with a pressure limiting valve. Suddenly our hot water pressure was a bit variable. I tapped the expansion vessel and instead of a half hollow sound it was all dull. Not sure why we lost the pressure... I...

    Does autodoc give good service?

    Definitely if HMRC - or whoever does it - slapps a huge import tax on anything bought outside england. VAT added to Aliexpress purchase, which did not exist before brexit, import tax on EU staff. The only question is about quality. Where is the brexit dividend?

    Private car parking fine

    Do not ignore it. Appeal through the channels provided. They may or may not follow on from their threats. I had one from PE even though I had paid the landowner and had proof. In the end I wrote to the MP and then PE cancelled, but only as a stupid "goodwill gesture" not because they were wrong.

    Water hammer from mid position valve

    The problem is solved now. Thanks for the help. After changing the pump we had a water hammer, only obvious a few months in when both CH and HW were on and CH call went off. The pump is and was fitted in the correct orientation - same arrow direction as the old one. The change that cured the...

    Insulated plasterboard, how much difference will it make to solid brick walls?

    We moved into a house - 1930ies with solid walls - with an extension - 1970ies with cavity wall insulation. The house had always been cold while the extension felt a lot warmer. I have insulate all the rooms in the house with 50 to 60mm dry wall insulation from Kingspan or Celotex depending on...

    99% indoor humidity... what to do?

    When you hit 100% humidity, the air is saturated. This is tropical or after a rain showers. What you experienced in the morning was saturated and cold air rushing in and cooling down the room air. Cold air can hold less moisture than warm air. If you have 80% humidity inside in a small room and...

    Water hammer from mid position valve

    The problem was solved by changing the pump modes on the CH pump, i.e. by reducing the overrun - I think if I interpret the manual correctly. Nothing else has changed and the water hammer is gone.

    Oil change on a fiesta zetec

    Axle stand or ramp. Make sure you only use the Ford oil. I think your engine has a toothed belt running in oil and it is very sensitive - tooth decay and engine failure - to the wrong oil.

    I know this thread is old, but the setup could be a cartridge fork, which have separate functions left and right.

    Internal Window Sills

    I really did not like the internal hardwood window cills in our house. At some point they all seemed to get knocked loose and I put granite ones in. Looks much nicer.

    Velux issues due to low pitch (essentially flat) roof.

    This is one of our roof lights on a fairly flat piched roof. The upstand is designed for completely flat roofs.

    How can I find a reliable composite door installer

    We bought an aluminium door which was suppy onla and I asked a local joiner to fit the door. He could then also fit some matching trims to blend it into the doorway. There is no magic to fitting them. Make sure you or your fitter foam out all the gaps to the brickwork to avoind drafty cold spots.

    Water hammer from mid position valve

    The pump orientation and position is correct as per istallation instructions. The bang is pretty much one bang, sometimes reverberates a little. When only one system is in use, i.e. HW or CH and the heat call goes off, there is no bang, only when the 2 operate together. I went through the...

    The boiler is an almost historic Potterton, still working, will go at some stage.

    Water hammer from mid position valve

    ABV - Automatic bypass valve? No. When the room thermostat clicks off there is a brief overrun and then we get the bang.
