  7 Questions
Q: I just received this pump do these pump come with pump oil already in them ?
by Ricardo Ayala from Michigan on July 27, 2016

A: Yes, the pump oil is already in it. You will see the sight glass on the front, the oil should be at the red dot- not higher or lower.

Q: I am looking for a pump to fit a Honda GX340 .
by Dennis Lillrose from Michigan on March 08, 2016

A: You have chosen a perfect pump to go on your Honda GX340 engine. This is fully plumbed meaning the inlet and outlet fittings, unloader, external bypass, and thermal relief valve are already installed so all you will have to do is bolt on the new pump, set the unloader, and you are ready to go!

Q: Are parts available to repair an EZ4040G General pump? I.E., need pressure relief valve, thermal relief valve, valve kit(pressure)
by R Cox on February 21, 2012

A: Unfortunately we do not carry any parts for this particular pump. However, the parts are definitely available. This pump is a rebuildable pump so there should not be any problems getting these parts replaced.

If you contact General Pump directly, they can refer you to one of their parts delaers to where you can get the components you need. General Pump can be reached at (888) 474-5487.

Q: Pressure-Pro Slap Happy General EZ4040G Replacement Pump w/ PulsarEZ Plumbing Kit ... 3/8 or 1"? Will this fit a honda 13 hsp Ec-Cell modle #ZR 3600 ...
sorry but still i want know ez 4040g will be fit on zr3600 and if so i will get my order thanks

by Anonymous on December 22, 2011

A: This pump accepts a 1 inch diameter shaft. There should be no problem at all connecting this pump up to a 13 HP Honda engine. That size Honda engine will definitely have a 1" shaft.

This pump is the EZ4040G model pump, the SLP version just includes all the plumbing that is needed for the pump to operate correct. These parts would include the unloader valve, bypass valve, and chemical injector.
by Brian, Product Expert

Q: Bill
What is the female shaft opeing? 3/8 or 1"?

Will this fit a honda 13 hsp Ec-Cell modle #ZR 3600

by Todd Wilson from Michigan on May 25, 2011

A: This is going to be a 1" shaft opening. This would work on the washer you have. The bolt pattern for mounting may not be exactly correct, but nothing a pump adapter wouldn't solve.

Thanks,

Q: have a shark hot water unit..sgp 40357e...will the pressure pro slap happy general ez4040g work properly with this unit ? thx
by Dave from Texas on March 31, 2011

A: This pump would be compatible with your machine as long as you have a 1" shafted engine. However, this model is a cold water pump. The max inlet water temp for this pump is 104 F degrees.
by Brian, Product Expert

Q: Do you ship this item to Australia? If so, how much would shipping be?
by Jacque on March 31, 2011

A: Unfortunately we do not ship products outside of the U.S. Sorry, I would be unable to quote you on shipping this product to Australia.

These triplex plunger pumps are a step up from axial pumps because their construction allows the seals to be replaces and the pump to be rebuilt when it wears out, where axial pumps can only be replaced.

You will spend more up front for a triplex plunger pump, but it will last longer and perform better than an axial pump.

Poor Product And Poor Customer Service (hold For Results)
The pump lasted about one month used it three times and the power dropped to about half. Waiting for Brian to get back to me. I told Brian of the problem and he said he would take care of the problem after he contacted the pump manufacturer. It's been one week with no contact. I left messages but no call backs. I then bought a $1800 pressure washer from Brian. The inlet water supply connecter keeps falling off. No return call on this problem either.
Cons: Unreliable, Durability

Howard,
I will contact you directly through your account; the folks at Pressure-Pro agreed to work with us on a refund for you.

Pressure Pro Slap Ez4040g-300
A half hour after pulling it out of the box it was ready to run. We slid the pump on shaft put 4 bolts in, tightened set screw
(small hole in housing) and it was ready to run.

It had very good pressure and was easy to start.
Pros: Easy To Use, Exceeded Expectations, I'd Buy It Again, Quiet

Great Product, Great Price
I run three machines, and one of the pumps failed a few weeks ago.

After quite a bit in Internet shopping I came across this General 4040 at a great price at Pressure Washers Direct. I'm not kidding when I say some places wanted almost twice the price, without an unloader- look for yourself.

Not only was it a great price but General backs up their product for five years. It's nice to know that General is watching over me; in 5 years I'll do over a thousand residential and commercial... more

I Am Slap-happy
I ordered the Slap-Happy 4040. I already had one of these pumps, so when it was time for a second rig, this was a no-brainer.

It comes with the unloader, by-pass, and thermal relief. It even had oil in it already. I pulled it from the box and it went straight to the motor. That fast and I was ready for work.

Shipping was fast and the price was fair. I will be ordering another one soon for a back-up.
Pros: Price, Exceeded Expectations, Reliable, High Quality

I Am Pleased
My pressure washer is 15 years old. It has an eleven hp Honda engine. It did not wear out, it rested out. I maybe had 40 hrs on the unit but it sat stored most of the time and age took its toll on the pump (neglect on my part) and it sat for three more years. It came time I had a strong need for a good pressure washer and so got online and started hunting for a new pump and found your store. 40 minuets after unpacking the new pump I had my old washer working like the old days. Couldn't be... more

Great Product
I had an extra 16 HP Vanguard engine laying around from a project that had never gotten completed. I bought this pump, used it with that engine and it was amazing. Everything bolted right up.

The only problem I had was at full throttle, the pump ran up to 2800 psi with the regulator fully tightened. Maybe my tip size was too big, but it still has plenty of cleaning power.

I would definitely recommend this pump for anyone interested in building or fixing a pressure washer.
