SaniSwift 0.3 HP Grey Water Pump

The Saniswift is model 021. Its design does not afford the ability to add an alarm. The Sanivite model 008 can be equipped with the Sanialarm model 050

No but the piping attached to it should be secured with appropriate pipe hangers.

I would suggest you give Saniflo’s technical department a call at 732 305 2200.

If you scroll down the Home Depot product listing page you will come to a section entitled Product Details. If you expand that section, you will find more details about the product including the following statement “Inside of the SaniSwift is comprised of a pressure switch and circuit board assembly, which starts and stops the unit, and the motor, which drives the pump.” As a plumber I consider a pressure switch to be different from a float switch. Some pump designs lend themselves to one versus another. They both perform the same function; they turn the pump on and off, but they approach it differently. Therefore, I would answer the question this way. The SaniSwifts on/off function is controlled by a pressure switch rather than a float switch. Float switches take up more space to accommodate the floats range of motion.

These are the steps I take when selecting an appropriate pump. First, I need to know what I am pumping. Is it gray water, effluent, sewage? Does it contain solids or semisolids. This information allows me to select the right category of pump. For example, if the pump is being used in truck stop used by many people, where almost anything could get sent down the drain or flushed, I may choose a grinder pump. Some of these pumps can chew and pass a beach towel or toothbrush. But if it’s only going to service a washing machine, I will select a gray water pump. Next, I determine what flow rate I need. Plumbing codes contain formulas for determining how much flow rate you need to have based on the number of fixtures the pump will service. Lastly, I need to determine how high I will be lifting the fluid vertically. We call this the head. Pumps fight gravity. Gravity is the strong force pumps need to overcome. Yes, the pipe and the fittings create some resistance but, in most applications, they are insignificant in relation to the head. I add 10% to the height for this when sizing residentially to arrive at “total dynamic head”. Granted if it’s a municipal application and you are pumping great distances an engineer will calculate the exact total resistance or pressure drop created by the pipe and fittings. But again, residentially the added resistance is typically just not that significant relative to the height of the lift. Once I determine these three facts, I consult the pump curve, which is a graph, for any pump I am considering. One axis shows height and the other flow rate. The curve on the graph illustrates the pumps performance across its operating range. Typically, one end of the graph indicates the flow rate if the pump were moving the fluid horizontally. Meaning no gravity needs to be overcome. The other end is the point at which the pump dead heads. This is the point at which all the pumps’ energy is being used to lift and support the water column, and flow has dropped to zero. I often describe it as the height of a wall where the pump can get water to the top of, but it can’t pump any over. I select a pump where my application falls within the center of the pumps curve. I try not to over size or under size. Both can be problematic in certain situations. Under the header Info and Guides you will find a PDF of the brochure for this gray water pump. It contains the pump curve. It indicates that at 10’ of total dynamic head this pump will move a little over 21 gallons of gray water per minute. At 4’ the flow rate is 23.5 GPM and at 10’ the pump will discharge 20.25 GPM. Hope this helps Chris 978 651 3301

If on a desk top computer, you scroll down the Home Depot product listing page you will come to a section entitled Product Details. If you expand that section, you will find PDFs of the product documents. The brochure indicates that the cord is 48”. However, you have indicated that you want the actual length. Therefore, I went to the warehouse and got one. From the tip of the grounding prong to where the cord enters the unit, I measured 50 ¾”.

This pump needs to be vented. Because the discharge is connected to the sewer line there must be a vent pipe to allow sewer gas from sewer to vent back to the main stack rather than into the living space. Further you cannot use a mechanical vent, aka air admittance valve, studor vent or pro-vent. This is because with pumps air must be able to move back and forth within the vent line.

The limitations to this product are 14’ vertical lift and a 140’ run. If you scroll down the Home Depot product listing page you will come to the section entitled Product Details. If you expand that section you will find PDFs of the product documents. The brochure contains detailed information on this unit’s capacity.
