My first question is that when filing the tank the top of the tank bulges up quite a bit. Have relieved the pressure by pressing the pin at the outside fill value. Is this normal? Secondly, it seems to take an hour to drain the tank and the reverse seems to be true as the top sinks and needs air to allow the water to drain quickly. Is this normal? As usual, do not have any documentation on the value assembly. Any guidance would be greatly appreciated.
First off, your holding tank should be vented to ambient via a vent tube typically exiting out the bottom of the unit. Secondly, there should not be a valve associated with this vent. The vent tube is also used to know when the tank is full as water will come out it when full. This input is for a unit that does not use a gravity fill for the holding tank, which yours sounds like it is. Check for a tube exiting under the unit that does not have a shutoff valve on it and make sure it's not clogged. If your unit has a gravity fill holding tank this is a moot input.
