A: Yes, you can. If you scroll down the Home Depot you will come to a section entitled Product Details where you will find PDF’s of the product documents. If you open the Installation Guide it has multiple illustrations showing fixtures connected to either side of the macerator.
A: I am not sure I understand your question. I am going to assume you are asking me how man watts the motor draws. If you scroll down the Home Depot product listing page you will come to a section entitled Product Details where you will find PDF’s of product documents. If you open the instructions you will find that this pump draws 4.5 amps at 115 volts. Therefore we know that (4.5 amps X 115 Volts = 517.50 Watts). So 517 and one half watt.
A: I would suggest you use a different strategy and do not do that. Pumping down is not a best practice. It will often result in air in the waste line that will cause the system not to work. I would plumb the bath with a conventional gravity drainage system to a low point where I would locate the sewage ejector. I would plumb it so the sewage ejection is only pumping up. This way the check valve is supporting a water column. When the pump cycles it will push waste into the column. That will lift it and force waste out of the end. Done correctly this will be much more dependable.
A: If you scroll down the Home Depot product listing page you will come to a section entitled Product Details. There you will find PDF’s of the product documents. It indicates 15’ as the maximum recommended height of lift which is referred to by plumber as head. However if you want more detail on the pumps performance please open the PDF of the instructions. It contains an image of the pump curve. A pump curve is a graph. On one axis is height of lift and the other flow rate. The curve or graph indicates the pumps performance across its range. You will notice for this pump when pumping 0-3’ up it will move 27 gallons per minute. When pumping 15’ vertically the performance will drop to 17 gallons per minute which is about where you would want to stop. If your application requires greater performance you would want to use a different product. The best practice is to calculate the head and the required flow rate needed at that height. Then select a product where your needs fall in roughly the center of the curve. Don’t under or over size the pump.
