If you're normally on a shoreline and only use a few lights and water pump, one of these should do: http://froogle.google.co.uk/froogle?q=drap...oogle&scoring=p For best results it needs to be located in the same space as the battery; it senses the ambient temperature to give an optimum battery charge voltage. I think most alternatives will require one of: 1) Spending a large chunk of money 2) Learning more about batteries than you ever thought possible 3) Wielding a soldering iron Or a combination of some or all the above. cheers, Pete.

Hi You might want to show it to the BSS examiner before they examine your boat, too. They might have their own ideas on what hose and check valve is acceptable too, so it could be worth clearing it with them beforehand. BTW has anyone experienced or heard of an engine fire on a diesel engined inland waterways boat, in the UK? cheers, Pete.

Hi, This may help: http://www.britishmarine.co.uk/DocImages/F...load.asp?id=302 It should start a small PDF download, if not I could upload it somewhere. cheers, Pete.

Hi, Just get some £5 powder ones from Lidl to get through the BSS, then work out what your boat really needs. It's no use wondering why the BSS says what it does, best to just get over it and move on... IMO the BSS could do with some sort of a 'source document' detailing the rationale/justification etc behind the requirements, but it ain't gonna happen I expect. cheers, Pete.

OK it looks like the wrong post was linked to. Basically that if calorifier manufacturer requires an expansion vessel to be fitted, then one should be fitted. Even if not required by the manufacturer, an expansion vessel is worth having to accomodate the expansion of water being heated. AIUI the PRV is intended only for coping with emergencies. cheers, Pete.

AIUI the PRV isn't intended to discharge in normal operation, it's more of a safety relief valve. I posted about this on u.r.w. a little while ago: http://groups.google.co.uk/group/uk.rec.wa...f3ff7acfa3be5fe cheers, Pete.

Hi, On my shower sump I've used one of these: http://cgi.ebay.co.uk/Brand-New-Johnson-L4...1QQcmdZViewItem together with one of these: http://www.toolstation.com/search.html?searchstr=51805 The above kit includes an elbow which gives more hose routing options. cheers, Pete. Edit: The pump comes with a threaded outlet and a straight union that screws onto it as shown here: http://www.johnson-pump.com/JPMarine/bilge/Cartridge_Duo.htm So you just screw the NRV onto the pump, and the straight union onto the NRV.

Hi All, I think the SmartGauge is based around a conductance tester: http://www.google.co.uk/search?hl=en&q=lea...G=Google+Search Basically it measures the conductance/impedance of the battery with an AC current to determine it's state of charge. Here's another example of one: <http://www.cadex.com/prod_testers_ca12.asp> That's why it needs to be connected with 1.5mm^2 cable. If it were a voltmeter then thin cable would be fine. cheers, Pete.
