:lol: I can piss more than that, thats nothing at this time of year, empty mine every 24 hours & it must have about 4 litres in at a time in a 5lt tank, try that in my tank room & you would make it 4 X's that, it all depends on the dehumidifier, some are tiny some are massive & very powerful, if I put the old one on I had it would be taking 10+ litres out a day, remember that once the moisture in the air is depleted it will start stripping it from the plasterboard, material & even wood, so its best not to over do it with them, sounds like your not able to with yours anyhow :lol: :lol: :lol: - stop panicking Grant, this time of year the moisture level in the air is pretty high.
