Offering all of the practical benefits of the 165 and the 345, the 465 Electric also offers the luxury of an automatic flush. Just push the button and the powerful flush operates instantly and effectively and continues flushing for as long as the push button is depressed. What’s more, the flush will operate more than 500 times before the six 1.5 volt penlite batteries (provided) need replacing (ideal if you're full of it). Dimensions are 414x379x419mm (HxWxD) holding 15 litres of fresh water and 21 litres of waste.
