Re: w/m with no time out on fill !!
…..also if the machine is taking water from the mains then the local water company are obliged to supply a minimum of 1 bar pressure anyway. Gravity fed supply requires at least a 7 foot head to give a similar flow rate. 9 times out of 10 most makes will cope fine such low pressures.
As for well water/private supplies then there could be many problems there anyway. So a tub and dolly paddle could be the way forward in cases like that! 😀
