Maintenance: Cleaning Mould (Mold) from Water Tanks and Fitting Filters on our Sailboat

All of our sailboat repair and maintenance blogs are now hosted on our dedicated maintenance channel, MOTHERSHIP MAINTENANCE Check it out here: https://www.youtube.com/c/mothershipmaintenance

An edited version of this video is now hosted there.

Scrubbing the Mould (Mold – sorry USA!) from the fresh water tanks of our boat – Urgh!

These maintenance video blogs aren’t to show anyone HOW to do a repair or replacement job – they’re just how WE did it with the equipment, resources, tools, information and skills available at the time. Some systems are unique to our type of boat – Amel Super Maramu – or some of you may know it as the SV Delos Boat.. yes it’s the same make and model!

So please use the comment section below to add any expert advice or experiences so we can all benefit and save money and time by repairing and maintaining our own equipment.

TRANSCRIPT

We’ve opened the water inspectionhatches just to take a quick look inside the tank and to our horror it was covered in mould (mold). Now, we’ve opened up a can of worms because we found that was three inspection hatches in three different compartments of the water tank and to get to all three we’ve got to move the dishwasher from under here we’re going to remove the pan rack here and worst of all we’ve got to remove this freezer unit which is completely plumbed into the compressor and everything else.

And there’re screws everywhere, there’re screws under the pan rack, there’re screws under the floorboards there’re screws on the side and there were even a couple of screws fibreglass in on this side nest to the compressor now Amels are quite unusual they’ve got the water tanks actually housed in the keel here and it’s in three parts but luckily each part has got its own separate access hatch all of the water has been stored in this three-part tank and the keel bolts actually fit in through the bottom of the tank.

So finally we took all of the screws out and we still couldn’t get it out but it turns out it’s just so tightly jammed in we’ve had to revert to a bit more brute force and jimmy the whole thing up and it just popped out. And so now we’re going to remove the whole thing and see what horrors we got down below. Every day we had to put things back so we could live on the boat and then take it apart again to clean out the tanks
and we use long scrubbers mops and elbow grease and detergent to really get rid of all of the mould (mold) before we felt that it was safe to use. The next thing to do was tee off the water pipe to put a fresh water tap in but previous owners modified their plumbing system so we had a mixture of Imperial and metric systems so it took some time to work out a relatively easy step of just teeing off a pipe.

Why are you changing them?

Well I’ve got a double one – the single ones under there and I want to use the single ones in the engine room So since then we’ve replaced the single filter with a double filter we’ve got a carbon filter on the left-hand side and the five micro filter on the right-hand side. I know a lot of people like you use a double filter before the water goes from the shore into their tanks but I’m kind of the opinion that a little bit of chlorine and the tanks isn’t a bad thing because it might hold that mould (mold) at bay. And we don’t have to replace the carbon filters much because it’s only filtering out drinking water and not tap water for washing up and showering in things that. So it goes through the carbon filter, through the five micron filter and then up to the drinking water tap.

No more more bottled water and no more plastic bottles.

Nice.
