WAYNE PC2 Portable Transfer Water Pump With Suction Hose And Attachment, Black

For the price, it is hard to beat this little pump. Like a couple of other purchasers, I used it to flush a Rinnai tankless water heater for 45 minutes per the manufacturer's directions. The pump ran flawlessly and was hardly warm at all. Here are some observations for those who will use it for similar purposes:1. The Wayne pump is suppose to be self-priming but the instructions say to prime it with a tablespoon of vegetable oil. I primed the input hose with the water heater company's specified flushing fluid (vinegar) and it started pumping right away.2. The illustration shows a transparent hose, but I received a 6-foot yellow garden type hose of high quality with brass connectors. It would have been nice to see the liquid flowing through the hose, but this was minor as I could verify the pumping action at the outlet end of the hoses.3. The pump comes with a replacement impeller, hose gasket, motor brushes/springs, etc. Nice touch.4. Mount the lightweight pump on a wood base to give it more stability. Otherwise, it will flop around every time your hoses are moved.5. Note that the pump inlet and outlet are male fittings. This means that to connect to the tankless water heater (or perhaps to another hose), you will need a female-to-female adapter. I made one out of a piece of 10' scrap garden hose with the original female fitting at one end and I installed a replacement female fitting (sold at Home Depot for repairing hoses) at the other. One end was installed at the pump, the other at the water heater. (Short lengths of hose with female connectors at both ends are available as hookup hoses for clothes washers. New ones sometimes appear in thrift stores for as low as $1.00.)6. Wear hearing protection when operating this pump indoors. While not ear piercing, it is noisy if operated inside a room.7. When you finish flushing the waterless tank with vinegar and then with water, don't forget to flush the pump itself with water as well as the hoses and fittings. The vinegar is dilute acetic acid and it will eventually eat away at the brass plumbing fittings if not well flushed with water.8. Finally, I noticed that there is a Hydropoint 1/10 hp utility pump similar to this Wayne pump sold by Amazon. It too is suppose to be self-priming, but I bought the Wayne pump because it had 10 times the number of feedback ratings and most of them were very favorable. While the Hydropoint may be just as good (it looks somewhat similar), I was not disappointed with the Wayne pump as it paid for itself the first time I used it.Update September 14, 2012: I again used this pump to flush the tankless water heater for 45 minutes. I did not prime it with vegetable oil or anything else to see if the pump is truly "primeless" as claimed and it sucked up the vinegar and pushed it through the water heater heat exchanger without a problem. I later flushed the pump with clear water from a 5 gallon bucket. It emptied the bucket in under 1 minute, living up to its claim of being able to pump about 340 gallons per hour. It's a neat little pump, already has paid for itself!Update October 5, 2016: This pump continues to operate flawlessly to flush the Rinnai tankless heater.

Unfortunately based upon the reviews of this pump, I purchased another pump where the reviewers said the pump was sized correctly for my application, and as I was in too much of a hurry to spend more time for such an inexpensive item. Subsequently I got that made in China pump, disassembled it to see how it was made and determined the HP was not adequate for rain barrel applications as there was not enough pressure through 100 foot of garden hose despite reviewers claims there was, and the pump while a nice design was very poorly manufactured. I then took the time to 'fix' my mistake of listening to people who should not have written a review and determined I needed between 1/2 HP to 1 HP to transfer water from from a 60 gallon rain barrel through 100 feet of 5/8 garden hose through a high pressure spray nozzle and to maintain adequate head pressure.I took a chance with this pump due to the negative reviews and found out they were nonsense. This is a very well made brush AC centrifugal pump. The quality of the pump manufacture far exceeded the other made in China pumps I examined. In fact I would rate this the highest quality 1/2 hp pump of the five I investigated and an outstanding value for 1/2 HP. It works by an symmetrical impeller rotating in an asymmetrical housing and creating a friction seal and pushing water through much like a windmill. Wayne went through a lot of effort to make this the industry leader per $.I use it 1-3 times a week to spray compost tea I make in the rain barrels on my gardens and fruit trees. At the end of the pumping the housing is barely warm. Sure I wish there was more pressure but it is adequate to spray up to 15 feet high, or higher if you shut the spray valve off and let the hose pressure build for 1 minute or so until you can hear the pump at near full load. And it pulls through a soft transfer hose with collapsing it.I suggest buying some quick connects to attached to the inlet and outlet ports and you will need to mount it on some 4x6 or other heavy board to stabilize the pump.This pump does not have enough hp for sprinkler application or if you have large tanks say over 60 gallons as it will take too long and you should go to 1 HP for that. You should use a very high quality 12 AWG/15 AMP type of extension cord if you're going to use this pump that is rated for outside and use as you don't want too much voltage drop at the motor. You might also want to consider a in line surge protector and short circuit protector rated for outside use if you're going to use the pump a lot around water to protect the motor and yourself.

This was my 1st experience with an electric pump for draining a waterbed. You MUST prime with a little vegetable oil before engaging. Read the instructions. It is very EASY to use. This pump gets hot, it's loud, & it pumps FAST. There is no on/off switch-you must unplug from outlet to shut off. It is a little difficult to get a good seal, might need better washers, as some water leaks out. Not a lot, but enough that I set it a piece of wood over a bucket to catch the drips. Overall, this appears to be a very basic but mighty little pump. Wayne is a reputable brand. I don't expect any issues with longevity.
