In the Spring my redneck water heater’s hoses were so full of loose scale I couldn’t get any pressure out of the spigot at all. Took forever to clear it all out. I swore that this time I’d take the whole thing down, drain the hoses and leave them on a slope for the winter. Doesn’t take long.
So for the record I did that this time. Putting it all back together will take much longer – but I’d almost certainly have to do it anyway, so this way I at least save the effort of clearing out the inside of the hoses.
