  1. My 'end of hose' gadget ....................
  2. To prime it (when there is no water supply) - take the face plate of the impellor, fill the pipe with water until it starts to run out of the pump. Put the face plate back on. Start to pour water into the funnel, get someone to stat the engine for you - don't wait for the level to drop as it will pump 'a pipe amount' in a second or three. (Yes you will be getting water into the bilge but unless you are in the water its goinf to be messy). Nest question : Impellors only spin in one direction, if you put them in the wrong way when the engine starts the vanes / fingers will be damaged, the tips broken off, or even the whole 'finger' ripped off within one revolution of the impellor. The impellor vanes must be bent in the correct direction to allow the rotation to flex them over the 'flat' in the pump. If they are bent the wrong way, then as the impellor is rotated the fingers need to turn in the space by 180 degrees - there is not room for them to do this, so the break off. Did you take a picture of the old impellor to show you which was to bend the fingers when you fitted it ? This impellor rotates anti-clockwise, so the fingers can bend back on themselves as it rides over the 'flat' in the pump (right hand side) That is what generates the pumping action. What happens to an impellor if you run it dry or put it in the 'wrong way'
  3. The impellor should be sucking (and 'blowing') water the instant it starts to rotate. You mean to say that the sea-cock was closed and there was no water in the pipe from the sea-cock to the pump ? Had you primed it ? If has rotated for more than a minute without water then it is (almost certainly) in need of replacement as the tips of the vanes will have burnt off.
  4. If a cell is failing and has an internal short you will find that the battery charger is working much harder (higher current) and for much longer that previously as it is, in effect, trying to put a charge in faster than it is 'leaking' (shorting) out, The acid will be boiling away, the battery case will start to get warm, the battery terminals will get too hot too touch and the battery case ends will start to bow outwards. The 'fumes' will start to corrode any metal in the vicinity and you may notice a 'greenish' tinge to the metal work, or even the start of a crumbly white powder coating (I'm sure you've seen it on old battery terminals). The longer you leave it the worse it will get - the final indicator of an internal short is when the battery actually explodes spraying hot acid all around the engine room, and, onto anyone who is standing / sitting / working in the area. Once you have identified (and accepted) you have a problem it can become quite dangerous, and very expensive to delay taking the battery out of the bank. Not necessarily to replace it but just make sure you disconect it.
  5. The Yorkshire Post ; Bingley Five Rise Lock: The incredible history of an iconic piece of engineering (msn.com)
  6. That is a considerably different figure to the C&RT 'Liveaboard Survey' - mind you, 'we' have always said that there will be a fair number who do not admit to living aboard for various nefarious, personal or tax reasons. I wonder where the programme got the information from ?
  7. I'm sure the fact that over 15,000 people live on Narrow Boats would come as a surprise to C&RT.
  8. It doesn't matter what colour it was painted, it'd still look rubbish (well just like a rubbish barge with a lid on) Awful !
  9. Me flying along Sutton bank in the 70s Presumably 'your Herriot' was just a conicidence as the 'real' Herriot was a ficticious character and was actually the pen-name of the author and 'star'of the books and series, vet, James Alfred Wright, the stories were just semi-autobiographical
  10. Its "everything", not just documentaries. The TV series it "Shouldn't happen to a Vet" and later series "All Creatures Great & Small" were based in rural Britain in the 1930's. In several episodes the Vets were seen treating Charolais cows which did not arrive into Britain until the 1950's. It is believed that the 1st known Charolais Bull in Britain was registered in 1967. The field hedges can be seen to have been cut with a Tractor mounted Flail cutter - with the 'bits' all over the verge and the road. Facts are rarely consideredwhen making 'drama' programmes. Its almost as bad as having jet aircraft high up in the sky !
  11. I think so - you'd pick up a tow. The coastguard wouldn't want an unlit NB drifting down the Mersey.
  12. Beat me to it - I was going to suggest that he is a closet 'bunny boiler'. Even on 'open' FLAs the 15+V charge mut be at very VERY small current levels and not maintained for hours. On my 1200AH battery bank I keep the 15+V charging to around 1 amp and only for a couple of hours. (I have a power supply with which I can exactly control both the voltage and the supply current)
  13. That was the way I started my old 3C JCB (no ignition wiring) - but - using a screwdriver. The sparks make you jump but you get used to it.
  14. Your suggestion appears to have no logic at all :- Maybe its because an engine breakdown, and the need to drop the anchor, is unplanned, unexpected & can happen in a split second, whilst the hours of darkness are normally fairly predicable, also, bad weather (Fog, gales etc) does tend to be forecast at least a few hours before it happens.
  15. This post cannot be displayed because it is in a forum which requires at least 10 posts to view.
  16. From an earlier (1999) Master Parts List/ Yes they had two different versions on marine engines :
  17. The Lister Petter master parts manual must be mistaken then, as they certainly call it a solenoid.
  18. Attached screen shot of LPWS spares manual, showing the starter solenoid and part numbers.
  19. A 1000 litres per second is not a small amount. or ..... 3.6 million litres per hour 86.4 million litres per day
  20. Surely if you can get the humane trap into place and get it out with a Rat in it, then you could get a non-humane trap in the same place. I agree - whilst poison is effective, having a dead Rat hidden away, rotting, is not pleasant. We do have quite a lot of Rats, streams combined with fields of Maize gives them a super place to live, but when they come around the buildings its time for poison, traps, or ....................................... (The 410)
  21. Makes one wonder why you use a humane trap in the 1st place - why not just get one that breaks their neck - saves you a lot of bovver.
  22. On the other hand, lets give a long-time moderator a bit of room, for not reading that the OP is not actually using a water-point / hose, but is pouring it straight into the tank from a 'Jeremy can'.
  23. Neither does mine - which is why I said TAPE THE HOSE to the anglegrinder.
