Does anyone know how to adjust the quantity of water being added when flushing electric head? One head is set properly and the forward head is too much causing the tank to fill quickly.

Orita,

Not sure about the 548 but our 575 has 85 liter holding tanks for each aft toilet but only a 35 liter tank for the forward toilet sullage tank. Is the 548 the same? This maybe the reason for the forward tank filling faster than the aft tank.

On my 575 (TECMA electric fresh water heads) you can set it to fill, flush and fill again, do a dry flush, or just flush and fill. We tend to just use dry flush and the default (fill, flush, fill). If your electric heads are the sea water flush heads Hanse puts in, I'm not sure how you set them similarly. Most do have some capability to do this, though.

I am not sure what is being asked, the toilet does not add the water, it flushes it thru as long as you are pressing the flush button. There is another button to add and flush separately but it also works the same way, the amount of added and flushed water depends on how long you are pressing those buttons, thats how you regulate it
