If it is the fresh water pump, an hour's labour plus parts will come to a similar price of a new one. Fit a new one.

I don't normally directly counter comment advice on the forum but as a time served plumber I would discourage fitting isolation valves either side of a water heating device unless a PRV is present or the expansion tank feed is within the isolations at least. If the valves were accidentally left shut and the the heater fired up, there would be a risk of over pressuring or even explosion which the overheat stat may not prevent. Friendly advice. Andy.

Go for the International Intertuf 16. The cheap ones like Black Jack etc are little more than bitumen fortified paints and are not the same.

Ah well. If there's no obvious leaks, monitor for now.

Has it been a while since the coolant level was checked? Just wondering if the the original low level issue was a gradual thing or a more sudden loss. This info will go hand in hand with diagnosing the secondary issue.

It would probably be useful to know the actual rate he wants so we can better judge/advise. If the builder originally wanted say £20 per hour and now wants £35, (a 75% increase) I would just let him get on with it if you're happy with the work to date.

Can I be there for the first light up?

Thanks for the comments and advice everyone. Seems that Advanced and Tayna are popular retailers. And most of the batteries out there in the £80 to £120 range are probably much of a Chinese muchness. Even the well renowned Yuasa brand may have slipped into this arena with their lower priced gear. My narrowboat is probably like many, and falls well short of being a perfect environment for battery well-being. So maybe another cheap set is the way to go. I'll give it some thought. Great info from a great forum. Many thanks.

Hi All, Hope everyone had a good Christmas. I would soon like to replace my narrowboat's 3x 110ah leisure batteries. Looking for manufacturer recommendations. Cheap 110ah leisure batteries appear to start at around £80 (ie SuperBatt) and go skywards from there. Has anyone had good service from any particular brand? Did a search and didn't come up with recent info. If its been discussed recently, feel free to point me at a forum link and instruct me to try harder. Cheers for now and Happy New Year for this evening. Andy.

While this thread ended a few months ago, I don't think the proverbial nail was quite struck on the head. I think MtB's suggestion is most likely, and in addition, most of the calorifier's water is actually back draining into the cold water tank due to air ingress at the small leak point (at one of the higher level fittings or a tap) Many boats don't have an NRV at the inlet to the colorifier and many more will pass back anyway due to wear or debris. Same with the pump.

Hi Bod, Looking through the thread, your Keelblack had been on two years and was still in good condition in March '20. You then hauled out in Feb last year (Feb 2022) and work was required. Had the keelblack been on 4 years at this point? Or was an additional coat applied in March '20?

Hi Guys. Thought this thread was worth resurrecting. Seems like Keel Black (paint) is still a relatively little known product despite the early testimonials on this thread being very positive. It's now 8 years since this product appeared. There are a couple of historic follow up reports (all good) and no horror stories what so ever. Surely there are now a number of interesting (and hopefully positive) testimonials from boaters who have had this product in the water for 3 to 4 years (or more) Hoping it's still a hit as my NB is coming out next year for re-blacking. The traditional bitumen (Ballistic) I used last time presented the usual challenges. This is the website if you want to take a look. https://www.keelblack.co.uk/ Andy.

It would be interesting to hear from any forum members who use a sea toilet, on the permitted rivers, to hear their ethical stance on the matter.

Thanks both. This fills one of the puzzling gaps in my inverter understandings. Andy.

Thanks Eeyore,
