Any body got any idea why my jets are leaking on my tripple  jet wand when the trigger is in the off position ie when im not extracting.
It works fine on extraction but when i release the trigger to stop the spray the jets have water dripping from them,but in the past no water would come out of them at all.
I have replaced the trigger mechanism with a new one as i thought that the rubber ring bushes had worn and were allowing solution through. But that has not fixed the problem other than slow the leakage down to small drips coming from the jets.
I have also cleaned out the jets ( they were clean anyway).
The problem is still present but dont know whats causing it..

Hi
Trigger mechanism itself has probably worn you should try over size rubber first or you can fit an in line one way valve and filter this would control fliud flow when trigger is closed

Best regards Nick

Ps yes I have both

I had  the same problem, I phoned my supplier who initially sent me a new seal and plunger . which didnt stop the leak . They then sent me a new complete valve .

Now its started to leak at the link where the single pipe splits into two i assume it just needs to be tighten up .   Paul

Chemspec wands have the same problem it is caused by to much pressure being sent through the valve, in the plunger you will see a small rubber washer this comes free from its housing and works its way up the pin a new rubber normally a smaller one solves this problem.

The other way that wands leak is that again the chemspec ones have a little gauze filter to filter any debri so it doesnt block up the jets, this needs cleaning on a regular basis, this could be your problem

Thanks guys
i have replaced the trigger so i will check the plunger rubber

Paul,

A problem with the rubber "O" ring on the valve stem would cause a leak at the valve itself. The seal that is causing the problem here is the washer seal at the inner end of the plunger mechanism.

When checking this seal check also the the set-screw that holds the dished seal back-plate to the plunger rod is tight and that the back-plate is not distorted. Whilst the plunger assembly is removed, look inside and you will see the circular mating surface against which the seal seats. If this is damaged the seal will leak.

I have to say after a year carpet cleaning and getting involved with this forum you are by far worth your weight in gold with your experience.
However this time you have gone over my head with terminology.
To recap
I have replaced the whole trigger mechanism as i thought that was the problem.But after replacing with a new one i find that there is still drip from the jets ( not as much though).
I have removed the whole T ( tripple jet wand) Cant find any other rubber washers ,gause or anything else.I have totally cleaned them out ( even though it was clean any way with no blockage) only to find that it still leaks slightly ( not as much but still annoying).

It never used to do this.

try some anti drip valves, placed inside of jets ,im sure this will cure the problem ,

or isnt it that simple

Jeff are you winding me up or are there really such things as anti drip values?
If there are such things as anti drip valves

Paul,

Geoff speaks not with forked tongue.

Most wands incorporate combined anti-drip valves/filters. normally located just behind the Vee-jet. These are spring-loaded ball valves which create a seal at the low pressures caused by the weight of the water in the piping from the trigger-valve, but open at the greater pressure delivered when the trigger valve is opened.

If the wand is left (vertical), with pump running for several minutes, and the water that drips from the jets is more that the total amount that can be contained in the pipe from the trigger valve, then the trigger valve is the culprit. if after a few minutes the dripping ceases then the trigger valve is OK. and anti-drip valves are the cure.

My previous post concentrated on the trigger valve since I had the impression that the dripping was constant. I have fitted new t/Valves that were faulty.

paul , definitly not winding you up,
now if i was going to  i am sure could do a much better job    BEWARE  LOL
