Cleaning water tank

[Silvercloud]

Just finished cleaning the water tank on my T36.
The tank is under the bed in the aft cabin and is easy to get at but here was no access or inspection port in the tank so I have just fitted a 150mm round port.
The inside of the tank looks mostly clear after a good dose of bleach but I think I will give it another go.
I will also cut another port in directly above the tank outlet to check what is there as I found the poor water flow was due to a partial blockage of the pipe.
I removed the inlet to the FW pump and connected to a mains pressure hose and back flushed and it now flows very well but the crap must be back in the tank.
I have also fitted a dedicated drinking water tap to the galley sink with carbon filter underneath.
Now for the plumbing for a freshwater supply to both toilets that I am changing .

I've also cleaned my tanks recently with two large bottles of milton fluid and they came up well. They were not filling or balancing well and I found that both tank vents were blocked - works well now! I also fitted an under-counter filter tap system from BWT (the magnesium version) and it is absolutely brilliant - no more bottled water and it tastes great. The BWT version is technically a home / professional product but works well and is much cheaper.
