I noticed that the silicone tubes pumping water from the tank have become dirty with a possible build up of fungus. They need to be replaced. Is there any guidance on this? Thanks!

i just open the top, you can pull the old tubes off, one off the boiler, and one off the pump - you’ll need to remove the pump to get that one off, and just push replacement tubes where the old ones were
