    That's what I did with the turned lock. I just put the kettle and waited. Normally I'd have gone up and helped open gates.

    It’s amazing how many things suddenly need a few minutes immediate attention when one is no longer disposed to go and help out :D

    Just curious - would water extinguishers survive sub zero temperatures if left aboard a winterised boat?

    The water mist units listed at Safelincs quote an operating temperature down to 0C, foam down to +5C. Both are marked “protect from frost”; you really wouldn’t want a an extinguisher pressurised at 12bar unexpectedly going pop!

     

    Of the available types, you could get to the BSS magic numbers with 3 x 2 litre 8A/55B foam extinguishers alone, but taking up a moderate amount of additional space versus powder. 
     

    Incidentally, has anyone fitted an automatic extinguisher in a cruiser stern engine bay? I had considered it, but the only option seems to be dry powder (the FE36 gas one has been discontinued) and the operating temperature is quoted as 79 ±5C. I know the calorifier which is also under there can regularly get to 70-75C-ish.

    this is what I think the BSS Regs should be:

    Take it up with BSS office then! In the meantime you are free to have pretty much as many additional fire extinguishers of almost whatever type you like, as long as they include a minimum quantity that meet the BSS specified requirement 😎

    NOTE – portable fire extinguishers manufactured prior to the introduction of EN 3 may not have fire ratings marked on the extinguisher. Such extinguishers maintained in good condition, properly certified and satisfying the navigation authority’s previous individual and total weight requirements are acceptable.

     

    I doubt if the BSS would reject 3 extinguishers that are far better than dry powder ones.

    I clicked the Safelincs link you provided and read the spec. They’re EN3 certified, and the 13A/21B fire rating for the big 6 litre is in the manufacturer’s data sheet. I also looked at the latest BSS doc, which is quite clear in the appendix that 5A/34B is the minimum acceptable rating for an individual extinguisher. The text you quote no longer appears in that form; the reference to the introduction of EN3 is replaced by “before 1980”. Whether they are “better” or not is immaterial; they don’t meet the specified criteria.

    How many of these, and of what size, would you need to meet the BSS requirements (e.g. for boats over 35 feet, minimum 3 extinguishers each rated 5A/34B?).

    None of them - even the 6 litre is only 13A/21B, so in the eyes of the BSS doesn’t count as a fire extinguisher.

  5. Predictable… Have they had two boats staring each other down bow-to-bow in the middle yet?

     

    The daughter and I narrowly averted a hire boat cilling there once. We were milling around lock side waiting to start down, and observed the hire boat in the top lock starting to adopt a worrying downward slope. Dropped the upper intermediate paddles a bit sharpish, somewhat to the surprise of the chap who had raised them and was no longer paying attention. Fortunately it wasn’t too far gone.

    Am I right in that point about that if you have a bubble-tester it negates the requirement for a Gas Safe inspector to still be able to achieve a BSSC?   

    Answering a slightly different question that you didn’t ask - my BSS Examiner advised that having a bubble tester with an instantaneous gas water heater was “not allowed”, and he would fail a boat so fitted if called upon to examine it. Something to do with the maximum rated throughput of the largest available bubble tester being insufficient for the throughput required by a gas water heater (possibly in conjunction with an oven and hob?). Or something along those lines, I’m a little hazy on the details as it was a couple of years ago, and the question only arose through a discussion on where to put the test point when I was revamping the galley.

     

    (I think the answer to the question you did ask is that a bubble tester would permit a non-Gas Safe registered BSS Examiner to carry out a soundness test on a boat which fell under the GSIUR regulations, such as a residential or hire boat (and some others). That Examiner would not be permitted to carry out a manometer test on such a boat. There’s more detail in the new checking procedures document on the BSS website.)

    Hi yes their online map

    If you mean the black markers on the ArcGIS reference map, they are 25m subdivisions of the kilometre lengths, but be sure to check the label as additional ones are inserted at junctions and the naming changes. This one is 12.125 km (i.e. 125m into the 13th kilometre length, the first length being kilometre 1) from the official “start” of the Trent & Mersey canal at the north end of Preston Brook Tunnel. There’s a bit more info if you have a root around the dataset definitions.

    Hmmm interesting. That appears to be a less strict requirement than specified in BS 5482-3:2005, which (IIRC) defines a let-by test and a stabilisation period of five minutes, followed by no discernible movement for five minutes. 

     

    I dunno what BS PD 54823:2016 says.

     As far as I recall there was a recent-ish change to standardise the BSS procedure across manometers and bubble testers, and the manometer test used to include two periods of five minutes. I’m sure someone who knows will be along shortly to clarify what changed.

    I've had a scan through the BSS to see what it defines as the tightness testing procedure, and basically, it doesn't. All it says is:

    "All LPG systems must be free of leaks when tested in accordance with the appropriate tightness test procedure", and thus we are looped back to the procedure defined in BS5482-3.

     

    There is a lot more detail in the new (still officially draft) ECP document on the BSS website - Appendix C, too long to post here, but the basic requirement for a BSS pass is “no discernible movement” on a fluid manometer, defined as not more than 0.25 mbar in 2 minutes. There’s detail on the bubble tester procedures as well.

    Just one other point. When you do get the multi plug apart, and after you have cleaned it etc etc. When you put it back together, put a thin cable tie round it ina couple of places so it stays well contacted and doesnt loosen in use.

    There may be a cable tie under the cover already, which would stop it coming apart.

  11. After the filter issues I had last summer, I made up a cleaning device using a length of 3/8” copper pipe, a length of clear braided hose, a small 12v vacuum (air) pump off eBay, and a large 25 litre plastic container. It was reasonably successful apart from the catch container having a tendency to collapse under vacuum - I really need some sort of much heavier duty thick walled container.
     

    Here’s the muck that came out. These are 10 litre containers, first lot on the right. If you look closely at the right and centre containers, you can see the water at the bottom. Left it to settle out for a couple of weeks, decanted the clean stuff off and returned that to the tank. Had a proper primary filter fitted as well.
