    LDV 400 Wiring

    Connor7932 I would still like a copy of the wiring and access to a manual would be really good! I missed your reply as I hadn't checked the site for a while. How do I get to it please?

    LDV 400 Wiring

    I have just bought a 1992 LDV400. I'll wait for the cries of derision to die down. The wiring seems a bit dodgy, with lots of insulating tape around twisted together wires and worse. Please, does anyone have a wiring diagram that could be emailed, posted or put in a bottle and sent out to...

    zip hydro boil

    You drink a lot of tea then! - It's a wall mounted kettle. Have you tried Zip? 0870 608 8888 or [email protected] They're in Dereham, Norfolk. As for installation, use manufacturers instructions

    cordless headset for watching tv, help please

    My father, who was partially deaf had several of these - In answer to your questions: The sound from the television speaker did not go off when the unit was plugged in - try it with normal headphones the connection is usually the same small stereo jack socket. The independent volume...

    here's a good one for you!!!!!

    Onetap, I don't want to argue with you. Between us all we have hopefully managed to solve someones problem and I don't feel a need to defend myself but this is what I mean: If you have a sealed loop of pipework which is, for arguments sake 10m from it's lowest to it's highest point then the...

    here's a good one for you!!!!!

    Well, you've proved that there was cavitation if the metallic noise reduces. The rest of the noise is general water noise - 2.7 l/s into a 40mm pipe will be in excess of 2m/s - I would normally design to 1.25m/s max. You could also look at how the pump is supported as this will have a...

    here's a good one for you!!!!!

    If the problem is cavitation the new pump will fix it. You have to be sure that you have eliminated all the other possible causes of noise. If you are confident of that then just to prove it try the throttling technique - you may need to close a downstream valve almost fully (but not...

    here's a good one for you!!!!!

    I don't have the 32-55 on my Grundfoss software but that may be because I'm a couple of years out of date. I do have the 32-40 and the 32-60, so I assume that the one they are recommending is between the two. The flow rate is certainly right, and the developed pressure against resistance is...

    here's a good one for you!!!!!

    Although a bit on the big side, the pump could be about right for your system, but only if both boilers are running - the 2.3l/s would match a system resistance of about 240 kPa, which is quite a lot (260 kPa if the pump is 3 phase). You really need to work out the system resistance to select...

    here's a good one for you!!!!!

    Belgiumboy - can you give some more info on the pump model - the UPS 200 covers a number of different pumps. If you can give the actual one I will look up the curves. This does sound like cavitation as the others have pointed out. This can really damage a pump in fairly short time. To get...

    Slave or Master

    Thanks for your advice, both. Some success. Having threatened it with a lump hammer, it sulked for a bit then allowed me to start burning my first DVD, I'll let you know if it is successful. Further information is that the drive is an Emprex 16x DVD Dual layer read/write/rewrite DRW11161M

    Slave or Master

    I have a fairly new PC which came with a CD r/w drive. My previous PC died shortly after fitting a new DVD/CD r/w, I've fitted this to the new PC as a slave, but I'm having problems. The new drive is listed as a DVD/CD r/w in the hardware list in XP but as soon as I insert a writable DVD it...

    Chainsaw blades

    Thanks, all. I've taken the chain and the bar off and will take them to a local emporium of all things sharp and nasty.

    Chainsaw blades

    I have a cheapish electric (B&D) chainsaw with a 350mm bar. It has had a fair amount of use and despite being regularly sharpened has now stretched beyond the range of adjustment. Unfortunately B&D do not make a 350 version now and do not list the blade as a spare part on their website. A...
