The only reason we do not endorse the univalve is that we are aware of the amount of damage that the use of them can cause to the components around them. We spend quite a bit of our customer service time assisting clients who have fitted them (as a modification) and then have other components fail - such as pole hose, push-fit connections, brush fittings etc.
Whilst we currently supply our twist gooseneck valve we are also working on a pull-action version of the gooseneck valve that will not have the same associated component damage issues we find the univalve can cause to other WFP components.
In the meantime we have designed a new standard gooseneck that will isolate the hard pulling action of using a univalve - this is in testing at the moment and will be released soon.
The above is a mystery to me
I have to say that since discovering your range of poles, goosenecks, brushes and brush fittings many years ago, I have never felt the need to look elsewhere for these tools.
I have also used the Univalve together with all of these products, including your green PU pole hose, since it was introduced and not had any significant problems or breakages due to the Univalve that were not easily put right with a little thought.
I’ve had two JG connectors pull apart in three years (cheap as chips and I always carry spares anyway) Fixed in seconds
If a hose has pulled out of a connector more than handful of times (usually only happens with hot water) I’ve fitted a JG hose tail to the hose. Again a simple fix
Even the issues with the Univalve and jet capsules were resolved following your advice.
The swivel and jet capsules together is another matter and a challenge I’m currently working on. (A different topic I know)
I am finding that using a swivel is problematic with the jet capsules especially in the colder weather. I have very little need for using hot water where I work, but I’m finding that as the temp drops the jet hoses become less flexible and this is pulling the capsules apart as I use the swivel. Lengthening the jet hoses helps but hasn’t completely resolved the issue. I’m going to try a softer hose option shortly to see if that resolves the issue
