I'm off abroad for a couple of months in 2 weeks, I'm leaving my boat on a winter mooring.
What's the consensus with the water tank, is it better to empty it? I've done this previously but would really like to have at least some water for when I get back. I was thinking that if I leave it around a quarter full the top of this remaining water will be a good 18 inches below the level of the canal. It won't then freeze and cause any damage. Is this right?

The water tank won't be an issue if you leave it as suggested.
Pipework, taps and pumps are a bigger risk along with a full cauliflower.

Is this right? We left ours partly full during the two very bad winters we owned the boat. Probably around a third to half full. The boat and tank suffered no harm. The tank was one integral to the hull construction. i believe some claim they had a large block of ice form inside the tank which sloshed and banged about but we never had this even when we returned to the boat when it was well below freezing. i can't comment on separate stainless tanks though.

It depends where the calorifier is situated. ours was inside under a bunk in the rear cabin, was never drained and also never suffered any harm. if it's under the rear deck hatches then yes agreed. we always drained the rest of the system though. Leaving water only in the calorifier and the main tank.

Water expands by around 9% when frozen, it can burst ball valves rated at 40 bar. I've had to put right hugely expensive damage to a steam generator caused by the failure of the site crews to drain it down.
Copper pipe bulges then splits in a most pleasing and obscure shape. Hep20 and the like fractures. Diaphragm pumps don't like having icecubes form in em!
If it were me I'd be more worried about stuff like that. Can you drain down post pump fairly easily?
I never leave our water system up together, but we don't live onboard so it ain't too much of an issue.

It depends how cold the winter is going to be! We haven't had a real cold spell for 4-5 years. The effort to drain down is easily saved if it gets cold enough to bugger things up. As Ricco won't be here to do anything about it sods law says it will be cold as buggery!

Two of the coldest winters in recent memory occurred while we owned a boat. We drained neither the tank nor the calorifier because of its location. All I can do is recount my experience. We did however religiously drain the rest of the system at the slightest hint of the temp. falling below zero.

What I'm thinking is: turn off the stop tap between the water tank and pump. Then; open all 4 taps, 2 each in sink and shower. Let water pump gurgle away for 10 or 20 seconds then kill it by flicking its dedicated switch off at the fuse board. Leave taps open. Oh, also pump water through the Thetford flush system until it fades. I don't have a calorifier.
Is that everything covered?

Martin it's getting tiresome arguing with you.
You hit lucky.
Ricco may not - just as we didn't at work, our kit is housed in a 20'container, remarkably similar to a canal boat tbh.
All pipework was lagged to prevent operators burning themselves and help steam efficiency - we still ended up spending thousands putting it right for the want of opening some drain valves.

Drain down your gas water heater. They suffer frost damage for fun. Take the shower head off as well. No effort required there!

I used to lag the pumps as best I could and I found by blowing down the shower pipe I could expel quite a lot of water from the pipe work through the bathroom sink taps. Disconnect the shower head and keep it in a safe place along with the rubber washer to do this. Don't reconnect till you return. Leave all taps open Run the shower emptying pump too to suck out any residual water sat in that. if you have a instaneous water heater don't forget to drain that, they are often the first to go 'pop' when it freezes.

Then why argue. Just put forward your view and leave it at that. i followed this advice because I got it on CWDF, and it was confirmed as the correct procedure by a multitude of other posters. i don't believe 'I got lucky' at all.

OK Martin, you win, I'm beginning to wonder if you are actually a woman, it's like having a discussion with one at times. I'm off to bed, night, night.

If that was your aim then fair enough. Just tidy up some typos and spotted your reply. That would be a no I'm afraid. You win is an expression of exasperation. I thought I'd refrain from telling you to fuck off as you seem to react badly to that.
