Wayne PC4 Pump - a fantastic pump 
Wayne 1/2 HP 115-Volt Transfer Water Pump, Cast Iron #PC4
This is a fantastic pump. For a half horsepower pump, it sure has a fantastic volume and speed capability. It’s equipped with convenient brass fittings to make most hookups easier. A terrific value, especially considering the reasonable price. Wayne also has a fine selection of accessories for use with this pump. A real good buy!
Powerfull pump 
I use this pump to empty an above gound pool. I purchased a sturdy 15′ hose for the intake and have had no problems. Like another reviewer noted, I had to buy an adapter for a few bucks to connect the filter onto the input hose end. I connect the output to my sprinkler system and get as much or more power then from the normal water supply. (after 30 minutes the sprinklers stopped, turned out their filters were plugged. Since then I’ve tied a screen around the intake filter to catch the small derbis and all it well). The only complain I have is that rust comes out of the output side for a few seconds each time I use it. The cast iron must be rusting internally. This may mean nothing or may cause a problem in the long term. For what it’s worth, I now empty the pump when I’m finished and spray WD40 thru the input/output holes. Overall, I’m very staisfied with this product.
Wayne 1/2hp Water Transfer Pump Cast Iron
Very well made. Very powerful. Two garden hose connectors in box. Used pump to purge air from hot water heat zone. It easily forced water through and eliminated air from a 100′ long zone that supplied a home’s second storey. I used rigid 3/4″ PVC for intake as pump’s suction caused intake garden hose to collapse restricting pump’s water flow. No state tax, Free shipping, and $30 less expensive than local rural stores. Arrived in four days.
Great product
The pump is pumping as I write and while it is much louder than the sump pump under my house…it is transfering water from 4 feet under ground out to the street 100 feet away. Primes quickly once you fill the pump via a bolt hole in the top. I tried to draw the water up from my inground tank using a contractor grade hose, but the hose was getting squeezed almost shut from the pumps suction. I went to the hardware store and got 3/4″ PVC and that works great…much better flow. Great product and it would have received 5 stars, but it is a bit louder than I expected…not a problem though since I will only run it 2 hours a couple times a month in the winter.
excellent utility, a little rough around the edges 
Once up and running, this unit will easily pump water at a rate equal to, or exceeding, typical faucet pressure. I have pumped water up hill 25 feet to power a lawn sprinkler for hours on end with no problems. While self-priming (once you’ve added water to the pump itself), I’ve found it can be slow to self prime with long intake hose or pumping up hill. I have also found that typical garden hoses cannot cope with the suction of the intake and tend to pucker and constrict –you’ll need a truly ridged and heavy duty hose on this end. This is not a problem on the outflow hose where any normal hose will likely work just fine. Be aware that his model requires some regular maintenance every 100 hours to maintain warranty. The heavy-duty metal construction of the unit itself has proven solid and durable. I was disappointed that the supplied intake strainer attachment used a male connector but the female connector is needed to connect the hose to the pump. Supplying an adapter or strainer with a female connector seems called for.
