Pressure Washer Info?

That's a lot for a Yorkshire man to spend!
Isn't it better to wash with cold water (in winter) anyway? The hot water dissolves the road salt crystals so they get into parts of the bike they wouldn't otherwise do.

 

The pressure washer is a pretty dumb animal. For less additional cost and impeccable reliability you could fit a dishwasher/washing machine spur and feed your cheap ‘cold’ jet washer from the DHW on those occasions you want hot water......or get clever with a blending valve for temp control.

Thinking about it, if you feed from an outside tap, you could internally create a selective hot/cold/temp regulated supply to the tap.

 

Pressure washers are great but best for ‘gross decontamination’ so detail washing can take place grit free and largely salt free. Maybe it’s me but I find:

Light soak overall (low setting)
Power rinse
Warm hand wash
Power rinse

gives the best results for least total effort. I am not into concours d’elegance sh1t!

 

Cold water washers do Not like being fed with warm / hot water, check your literature, the cold water is generally used to cool the pump & motor whilst its running / idling depending on the type of machine. Most have plastic valves & guides which don't do well in hot water ( sticking & seizing ) and pressure control parts.

Draining down after use is a really good idea, run it dry for a few seconds to clear the pump, at this time of year especially !!

Plastic hoses kink easily and wear through faster than reinforced rubber ones and none of them like being run over as it puts a sharp corner in the reinforcing braid causing a weak point prone to failure.

I personally don't like using pressure washers on bikes too many exposed seals etc, ok for washing off wheels but would keep it away from bearings and chains and most of all electrics none of which do well on high pressure water.

Having worked for KEW ( now nilfisk / alto ), Karcher & Gerni / Wap over the years was an education. Some machines do well on pressure fed systems ( mains pressure from the cold tap ) others run better on a gravity feed from a barrel.

Have a good read at what the manufacturer says they are not all the same.

Good Luck

 

Comes as standard on the "Blitzkrieg Pack"

 

I've had several different brands and models imho any nilfisk washer is ideal,even the basic models from machine mart has a metal pump and lasts for years,better than all the brands I've used before inc karcher/halfords/bosch etc.

 

There are so many different models and standards of machine made by the manufacturers now that the only way now is to research the exact model & specs of the machines you are interested in as they vary so much even within the same model numbers.
Even detail changes in models can have significant effects on performance and lifespan in the domestic market, many of these models are built to last a set number of running hours, with some being as short as 40.
So no reccomendations in this particular minefield, I specifically made only general comments in my original post for this exact reason.

 

Very fair observation. I suspect Karcher are trading on a reputation built 15 yrs ago.......
As to my ‘hot’ post I am guilty of forgetting my own DHW is already anti-scald and entirely accept your comments about hot plastic!

 

£2.00 at Sainburys pressure wash every so often whether it needs it or not ( it always does) and again before MOT time because where I live the farmers spread muck year round and I would rather ride than clean as anyone who has seen my Trophy will know.
