Hep20 valve is dripping in off position

[Jupiter01]

My washing machine has been discconnected from this valve as it is being repaired. This is currently in off position but is still dripping. I assume it’s faulty and needs to be replaced? Do I use the same fitting again?

Thanks in advance.

If the valve is passing when its fully off ,it's worth replacing ,but not essential.
You could fit a 3/4 cap to it in the short term .

Got a dripping one the other day, exactly like yours.
Is this another company going cheap and still charging top price?

Awful things, never come across one that doesn't leak. Better to get a brass one on there

As said, horrible plastic junk, change it for a brass valve.

one of these?

I assume this will fit onto the hep20 plastic pipe with the insert in place?

Thanks all. Replaced with a brass fitting. The dripping has stopped.

Out of curiosity (I’m that type!!), I just unscrewed my dishwasher from its hep20 valve and guess what? it’s dripping too!!!!

At this point I was captured by my heightened sense of curiosity. I purchased a new Hep20 machine valve and replaced the one on the dishwasher. At first, the outlet was bone dry since it was in the close position. Stuck my finger in the outlet a few hours later and this is dripping too. Unbelievable!

I wonder if I am doing something wrong...
I’ve just got some hep20 pipe under the kitchen cupboard. It’s using the inserts (not that there is any leak at this join) and it continues to drip at the outlet.

I would love to hear your thoughts/suggestions on this.

Yes ,you are doing something wrong....

How high is your water pressure? If you have a brand new fitting and it's leaking then it would be a return or a call to Wavin.

How high is your water pressure?

Cant imagine it's very high as I remember when we were having the megaflo installed, it was touch-and-go on whether we are getting the right amount of mains pressure.

I have emailed Wavin and will let you know what they come back with. Their technical support line appears to incur a premium charge!

Appreciate the point and I suppose it's "lesson-learnt" in my case! However, I know there are so many plumbers (surprised someone hasn't jumped to their defence here) who will happily use Hep20 and in many cases prefer it over copper. Irrespective of where you are on that debate, surely a machine valve should perform its very basic function of stopping water when set to closed. the fact that I have seen this with 3 separate fittings now (1 only purchased yesterday), I am astonished.

some people are more easily astonished than others it would seem.
some people even go looking for astonishment.
