Q: If I buy the Karcher X Series 1800 psi pressure washer, must I buy this extension hose (2.642-588.0) or can I use the Karcher PN 9.162-306.0 which I bought for my Karcher K2.900. My 2.900 is kaput.

by Richard on February 26, 2012

A: If you are looking to use an extension hose with the Karcher X series machines, you will have to buy this specific extension hose. The Karcher X series units do not have the same hose connections as previous Karcher models.

Q: I have Karcher Model K5.68 power washer and I need a Extension Hose to make it longer.
by James Pierce from Virginia on June 04, 2011

A: This hose will not work, you would need to use the 2.640-850.

Thanks,

Q: I have a Karcher K5.740
The garden hose connector cracked and I cannot find the rreplacement piece
Its actually the water inlet with connector that needs replaced
Where can I find this part?

by Steven Drexler from Pennsylvania on April 30, 2011

A: If you are referring to the quick connect adapter that comes with this unit, you can always purchase a metal garden hose quick connect kit that would be more durable. Unfortunately we do not carry the exact replacement adapter from Karcher.

If you are referring to the actual threaded water inlet that is attached to the machine, unfortunately we do not carry that type of part for this model pressure washer. If that is the part you are referring to, please visit www.pressureparts.com . They will more than likely have what you are looking for but there is a chance that part cannot be replaced.

If the garden hose quick connect adapter is what needs to be replaced, I am posting a link below to a product that would be compatible.

Q: Just bought the Karcher 3.74 from you guys. What is the "Pump Guard" which is recommended for storing and protecting the pump? And how do I use such?
by Preben Jensen from California on March 24, 2011

A: The Karcher pump guard is a chemical that is designed to extend the life of the pump and the seals within. Pump guard or pump saver as it is also called, will lubricate the seals in the pump and also prevent any water that is left inside the pump from freezing during the colder months.

To use this product, you simply attach it to your garden hose water inlet fitting and turn the machine on for a few seconds. Once the chemical exits the outlet high pressure fitting, the pump is protected.

You should defintely run this chemical through the pump every time you are going to store your pressure washer away for extended periods of time such as over 30 days. You should also run this chemical through the pump periodically throughout the year to keep the seals moist.

Don't Have To Move The Machine As Much
It helps so I do not have to move machine so much but will not come off of factory hose, and it also made the pressure weaker.
Mike, the Pressure Washer Expert

Frank,
The farther the water has to go to get to the nozzle, the more it loses pressure. Adding pressure hoses or long extension wands will mean less pressure at the nozzle.

How noticeable the pressure drop is depends on how powerful the pump is.

Good Product
I recently purchased a Karcher X Series 2000 PSI Pressure Washer. The first time I used it to clean my birdcage and pool area, it was a bit of a hassle with only the original hose.

I purchased the 25' extension and cleaning the area was a much easier job. The only thing I wish was different is that the extension would wind up on the roll with the original hose.

Works Well
Used washer several times and works very well.

Hose is a great addition to the Karcher washer. Allows me more freedom to move around and not have to move the washer, water hose and power cord.

Brush works fine on deck and concrete porch.
