SaniBest Pro 2-Piece 1.28gal Single Flush Elongated Toilet with 1hp Grinder Pump in White

A:  Based on your statement I do not believe I can effectively envision your installation well enough to offer a definitive answer and don’t want to give you bad information. So let me respond in a different way. Pumps are rated on graphs called pump curves. On one axis you have height and on the other you flow rate. The curve illustrates pump performance across the possible scenarios within its performance range. Pumps fight gravity and the higher you lift the fluid the less fluid they are able to move. First I would calculate what flow rate you need. Second the height of the lift. Then look at the pump curve to see if the pump will supply the correct performance in that application. 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 installation guide you will find the pump curve on page 2 labeled as figure 5. Next to it figure 6 Saniflo provides another table. It gives the limitation for runs following different heights of lift.

A:  These emails are routed to the supplier not to Home Depot. I am pretty good at technical questions and I am a plumber by trade. But I am not well versed at pricing strategy. I am always amazed at how similar prices are. Typically the pricing computers make them match exactly. I will send an email to product manager of this product so they are aware. Thank you for your feedback it is appreciated. I understand. I will pass on the information and I am sure they will address it. Sorry for the inconvenience.

A:  Yes technically, but you won’t be able to service it without an access panel.

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. If you open the brochure you will find this product installed the way you describe on page 14.

A:  we installed this toilet about two years ago. Hid the grinder in the wall and left access panel on on back side.  We have had to service the pump so highly recommend leaving access.

A:  Pumps fight gravity. When sizing a pump it is all about the height of the lift. We call this the head. Every pump is rated on a graph called a pump curve. On one axis you have height and on the other you have flow rate. The curve represents the pumps performance across its entire range. You want to calculate the total vertical height of the lift and compare that height on the two pump curves. If you scroll down the Home Depot product listing page you will come to a section call Product Details. There you will find the PDF’s of product documents. If you open up the specification sheet of both pumps you can compare the performance graphs. As to distance. Pipe running horizontally provides very little resistance. In fact water wants to spread out across a horizontal run. Granted when I am sizing pumps that will be moving fluids great distances, such as miles, I will calculate the coefficient of drag and take it into account. But residentially, compared to height it is irrelevant. So why does Saniflo mention it. Because the fluid contains semi solid waste. Their concern is that if the run is extremely long and the unit is only used intermittently the fluid could solidify causing a clog and because of the weight of a possible water column that is 150’ long. If I were dealing with a run longer than 150’ I would not use this product or style of pump. Not because of pump strength but because it is just not meant for that. I would use a more traditional sewage ejector station which uses larger pipe size.
