    Undersink heater, when is expansion vessel needed?

    Thanks Matt, that does more sense now I'm reading it right. As I've plenty of room to relocate the heater, I'll site the thing over 3m from the closest tap & save the 50 notes for an expansion tank I think. Cheers.

    Undersink heater, when is expansion vessel needed?

    Hi, We've got a small industrial unit and need hot water for 2 sinks so have got a Hyco speedflow 10L unvented heater. The instructions mention that if the nearest draw off for cold water is less than 2.8m away then no extra parts are needed, but that an expansion vessel & check valve is needed...

    Readymix or self mix?

    Thanks Wavetrain, I've got quite a bit of hardcore already. I thought I read on here somewhere about not putting hardcore in the footings? Does it affect the strength at all?? I can see the point though

    Readymix or self mix?

    Afternoon, We're putting up a retaining wall in the garden, footing are dug and I'm getting confused about volumes? Area of the trench to fill is 1.8 m cu Quotes for readymix are between £238 - £275 Sounds expensive, I can borrow a mixer but cant figure out exactly how much aggregate...

    Thanks very much for those tips I'm grateful for any little pointers, my enthusiasm often outweighs my ability :wink:

    Footings dug out - flooded, now a moat!

    On the soil-side of the wall? ...yeah i knew that... :oops: This is where i expose my ignorance, what are the pipes called that are found along the base (at intervals) of such a wall to let water drain thru? Is that the drainage that is needed? The foundations are about 500 wide, the...

    Footings dug out - flooded, now a moat!

    The wall is seperated from the back of the house by a patio, and is about 4-5m away. There was no drain there originally, so I'm planning on fitting a drainage channel at the edge of the patio. It is a 50's semi - but i cant think why no drain was put in to start with?

    Footings dug out - flooded, now a moat!

    Thanks. A friend of the wife has a builder husband, he advised to go 600 deep. I only got to about 500 when the water started to appear, so stopped. The wall will be about 1500 high, made with 7N blocks layed on their sides - as directed by the friend. Length of wall will be about 4m. Cheers

    Footings dug out - flooded, now a moat!

    Howdy, I'm replacing a retaining wall in my garden with a bigger one - the garden above is sloping towards it. I dug down half a metre and stopped when the soil became wet, ready to pour contrete onto a hardcore base. The next day 2 inches of water were at the bottom of the trench, and has...

    Rad bleed valve nut snapped off! now what?

    Thanks Dubya, No you didn't misunderstand, the rad does have valves either side. If I turn both valves fully off, will I just end up mopping up the contents of the rad itself when I disconnect it? I didn't think of that, as have always drained down first, bloody cheap Wickes valves!

    Rad bleed valve nut snapped off! now what?

    I need to drain my rads to get one off the wall to tile behind Simple enough, but upon opening the drain valve with my hose ready to take the water away. The poxy little square nut on the valve sheared off in the spanner, leaving the valve useless and the system still full. I'm at a...

    brake pedal spongy after pads change

    No, the fluid certainly didn't fall much lower than than the max level, so didn't introduce air that way i think? This was a week ago, and have driven 200 or more miles, so the pads must be bedded in fully by now, wouldn't you think?

    brake pedal spongy after pads change

    thanks guys, the discs are both good, the pads were the most expensive on the shelf. I checked a second time that the pistons move by pushing the pedal lots to extend them before pushing back with the Gcramp, covered by a bit of wood to push in evenly. Only other thing is the rubber boot...

    brake pedal spongy after pads change

    Hello, I recently changed the front pads on my '02 530i - which i've done on loads of previous cars. I even syringed out the excess fluid from the reservoir so it wasn't overfilled afterwards. Trouble is the pedal is spongy now, and travels much further than before to achieve the same force...

    Boiler extinguishes after a few seconds?

    :oops: well...... i've been here nearly 4 yrs, and not serviced it yet :oops: point taken, i wouldn't leave the car that long. we're doing the place up and there is always something that needs money spending on it. It is a noisy beast - but i'm scared of the replacement cost, we're only...

    Boiler extinguishes after a few seconds?

    Hello from a cold house :( My back boiler is playing up and i really hope you can help - a new boiler would be an unwelcome purchase. It's a Glowworm Majorca 3 - It lights ok, but goes out after only a few seconds, any ideas? Thanks in advance.

    Draining rads when you've lost the drain valve?

    Sounds a bit stupid I know...... A plumber 'mate' changed a radiator for me a year or two ago - the very rad that had the drain valve on it. I've only just realised recently (now i want to drain the system) that he must have moved the drain valve to a position that is now underneath the...

    Sink near socket

    Is there a legal minimum distance that I need to leave between my sink and a new socket I'm installing? I guess there must be, any ideas? ____________________ moderator 6a :wink:
