User questions & answers

Question:	What's the PSI or max head (pumping vertical height) of this pump
Answer:	A quick Google search of "Superior Pump 91250" yields the manufacturers specs. I do not see PSI listed but "Pumps will lift water up to 25' of vertical height" I belive answers your question...there is a chart on the "Performance" tab that shows 30 GPM at 0' lift and 2 GPM at 25' lift...with flow rates every 5' listed.http://superiorpump.com/products/utility/91250.html
Question:	Does it have an automatic shut off
Answer:	The pump does not have an automatic shut off. I added a float switch because I wanted it to pump out a sink that had a slow-running clogged drain where I had the washing machine. When the sink was mostly pumped out the float switch turned off the pump. It worked great for a couple years until I got around to dealing with snaking the drain which didn't have an easy clean-out. This is a good pump, since the sink drain got taken care of, we've been using the pump to pump koi pond water over a 5' fence to our neighbor's garden using about 150' of garden hose. The pump runs continuously for 5+ hours without issues in this process.
Question:	Will clothes washer hoses fit on this pump
Answer:	The pump itself fits a garden hose nicely. You can buy the attachment package listed next to it for the converter piece. It only came to around $8.00. It also comes with a larger hose. I didn't need it for my spa but if you need to empty a washer or bigger pool it seems like it would come in handy. Hope that helps. Good luck. :-)
Question:	Can this be user to flush a tankless heater with vinigar
Answer:	I bought the pump for this very reason. I'm not sure if it is rated to handle vinegar, but at the price I figured I'd try it and see. I have two tankless water heaters, and I wanted a pump that could clean out both at the same time and this pump certainly does the job. I have a hose that runs from the pump, into a splitter. From the splitter I have two hoses going to each water heater (one hose per water heater). Even pushing water through two hoses, it still has a strong flow, with each hose pushing about the same flow as the water hose faucet outside your house opened wide open (guestimate). The splitter I have allows me to adjust the flow rate by closing off some valves if it is too strong. For just one water heater, i would think this pump is too strong (as it REALLY moves water), but I'm not a plumber so I couldn't say for sure. If I were to do it again, I think I would have purchased the 1/4 HP pump, or even the 1/5HP for cleaning out water heaters with vinegar. I cleaned out my water heater this week for the first time using this pump. I let it run for 2 hrs, and I noticed that it got warm (about the temp of a warm-to-hot bath). I'm not sure if that is normal, but thought I'd let you know.

Product description

The SANISHOWER allows you to install a shower where you never thought possible. It gives you a fast and easy way to add an additional sink or shower to your home. It is a small gray water pump that may be used to pump waste away from a shower or sink. The SANISHOWER is small enough to fit inside a wet bar cabinet, or even beside or underneath a raised shower base. It has two inlets for installing a shower or sink and it will pump up to 12-Feet high and/or 100-Feet away from a soil stack. This pump can be installed in many locations such as a loft/attic, upper floor, ground floor, basement and even a converted garage. This product is ideal for installing a shower and/or sink in a bedroom or basement. As a point of interest, quite a few pedicure manufacturers are putting the SANISHOWER inside pedicure chairs. Due to its quiet operation and ease of installation, they have become the choice of OEM's. The inside of the SANISHOWER is comprised of a pressure chamber, which starts and stops the unit, and the motor, which drives the pump. When water enters the unit, it activates a micro switch in the pressure chamber, which in turn starts the motor. The motor is sealed for life in an oil filled enclosure. A spindle/shaft drives the impeller and therefore the moving parts are kept to an absolute minimum. Water enters the chamber and is pumped away into the sanitary sewer. The discharge elbow on the side of the SANISHOWER can be rotated 360 Degree to fit any type of installation required. A non-return valve, which comes already assembled on the discharge elbow, prevents back flow into the unit. This unit has been designed with a vent output on the side of the unit. All plumbing codes require connection to a vent system. Please note that the vent system should be a two-way air vent. It is also highly recommended for the gray water pump to be connected to a Ground Fault Interrupter circuit.

• Discharges 14-Gallon per minute.Horsepower 0.2
• Vertical pumping up to 12-Feet and 100-Feet horizontally
• Easy to install
• Small enough to fit under the shower base
• Ideal for light-duty applications

User questions & answers

Question:	Would this work for a washer
Answer:	Handles are great. We don’t carry super heavy items, no more than about 12 pounds. We have had them in the back of our suv for quite awhile. We shop 45 miles from home and just carry from vehicle to house with no problem!
Question:	Does this unit need to sit below my shower unit or will it pull the water out of the shower unit
Answer:	I picked up a bunch of frozen food and had a stop to make before I could go home. The drive home from the grocery story was an hour and I stopped to visit someone in between for about another hour. I left these bags in my closed car, windows up on a 75 degree day. By the time I got home my food had been in these bags for about 2 1/2 hours and everything was still frozen. These bags are great, easy to stack things in and easy to carry in from the car. I highly recommend these bags.
Question:	can this be use for normal toilet
Answer:	Yes I used them while doing instacart after sending photos that where approved.
Question:	I am putting a bar sink in the basement and need to pump the water horizontally 10 feet and then vertically 8 feet. Will this pump handle this

User questions & answers

Question:	Can this pump be hooked up to a battery backup
Answer:	It pulls too much current for most battery backups, a generator will run it fine.
Question:	how long is the power cord
Answer:	Just received my Wayne CDU980E. I, too, was concerned with this question. Power cord measures about 90-inches (7.5-feet) from where it connects to the top of the sump motor (which is about 11-inches above the bottom of the pump). I can't find this marked on Wayne's literature for the CDU980E.
Question:	When the pump is switched on by the floater, how long does it run
Answer:	If there is merely water in the sump pit, you don't need this powerful a pump. This 3/4 HP pump is for handling major water flowing into the pit. When that happens in our cellar, the pump runs until it out-runs the flow of incoming water.-- sometimes for minutes sometimes for hours. We have 4 sump installations in 4 buildings. When the water table (level of the ground water in the outside ground) is high, three of these systems pump a lot of the time and pretty constantly. We have 2 pumps in each pit so if one fails we do not get flooded. Each Pump (if more than one in the system) needs to have a check valve/ back-flow preventer so it will force the other pumps to actually pump the water up and out and not allow an operating pump to to just pump back out through the other , (not then pumping) pump. The should also be placed at different levels so they don't necessariy go on at the same time, thus reserving one as a kind of back up. Of course, if there is really a lot of incoming water -- which we had when we first bought our house, it takes both pumps to handle the in flow and avoid flooding. NOw that we use the large diameter PVC piping, it works so much better that a single pump pof this size would probably be fine. It is best to pipe the pumps with real PVC pipe and in 1 1/2" or 2" size. This will increase the flow rate by around twice as much flow as the skinny (1 1/4") highresistance black curly-sided plastic pipe they often come with. Good luck and stay dry.
Question:	when you say 'top suction' does this mean the pu,p must be totally submerged
Answer:	The pump draws water from the "LOWER" part of the pump a few inches off the floor. It does not have to be completely submerged to draw water. When the bulb float rises enough to turn on the float switch it sucks water. It turns on before the water reaches the top of the pump. I use this one and I know. Hope this helps someone.

User questions & answers

Question:	What is the AMP's on this unit
Answer:	On Amazon:)
Question:	Is the 3E-12nr pump continuous duty pump
Answer:	The handle strap and arm strap can make the distribution of weigh feel different. I'd say no it doesn't feel heavy. Different things weigh five pounds, it all depends on how it's distributed. A dumbell could be 5 pounds and so could a baby, yet they both feel different. I usually fill my bag with 2 1lt mason jars w/ water and smoothie and the large tupperware of food...that can heavish, but i'm only carrying it from the house to the car to the office floor. The bag itself is very light without anything inside. :)
Question:	Does the inlet fit a standard garden hose threading
Answer:	Yes
Question:	Does anyone know the sound level of this pump compare to other pumps
Answer:	Yes this requires an ice pack but I like the convenience of the two sizes.
