1st off i'll explain my situation in needing to use this suction hose!.
My car is away from my house so i have to use a VERY LONG extension lead to power my Karcher K4 pressure washer and i cant really use a hose connected to my outside tap because of the length!. Hence the reason for buying this suction hose, so i can use a bucket or BIG jerry can bottle(yet to buy!).
Anyway after getting this item through the post i have had a absolute nightmare trying to get this hose to work. I have read that just put the filter end in the water and it will suck it up, IT WILL NOT do that!, i have tried!!!!. I then "primed" the hose full of water, but yet again it WILL NOT suck any water through the pipe. Even just letting run for a minute as others have said still does not do anything. In fact earlier on trying to do this my pressure washer got so hot it shut down and wouldn't start for a good 10 minutes(the machine is water cooled!).
This is what i figured out that works 100% every time i do it!. The main reason this WILL NOT prime properly is the filter on the end is restricting the flow of the water!. IMO to start off the machine needs maximum water flow to enter the pump to then build up pressure which in turn starts the "sucking" process!.
What i do is....................
1. Take off the filter on the end of the hose(give a small twist and it comes of easy)
2. Place all the hose in the water to prime it as normal
3. Wait for the hose to fill with water, as seen by the air bubbles escaping(Because the filter is off, the water flow in the hose is A LOT better)
4. When done connect to the machine
5. Turn on and press the trigger on the gun
6. Again because the filter is off you will see the water being sucked into the machine faster and it will build up pressure
7. Reattach the filter and you are good to go!
I tried this 5 times in a row and EVERY time it worked for me 100%
If you plan to use this method in a water butt i would suggest priming the hose in a bucket of clean water first, then after you reattach the filter you can then put it in the water butt. I think once the machine has sucked water and built up pressure you should be able to move the hose into another water source!
Anyway there you go. I've gone from hating it, to loving it, once i sussed it out lol
5 STARS
EDIT, 20/01/2019 - Used the suction hose for the 1st time cleaning the car with the aid of a 30L plasterers bucket i got from B&Q and it worked like a charm!. In all i filled up the bucket 3 times(1 for doing the snow foam, 2nd for rinsing the snow foam off, then the 3rd for rinsing the car shampoo off). Just make sure the water doesn't run out of the hose before re-filling your bucket as you will have to prime it again!
