Univalve! Leaks! New One Does Too!

Edward Baskerville said:

I’ve had univalve for 2 years now and the mechanism went inside it and I bought new one. I noticed couple months before I bought new one it always leaked! I’ve recently fitted the new one and that leaks too! I’ve tried everything re-positioning of the clips clapping slightly/tightly. It just seems to leak no matter what. Could the setup of my controller and pump have anything to do with it? Need Help!

Send it back under warranty for repair/replacement. You could also just open it and lubricate the large O Ring with a smeer of vaselene.

They told me to return mine for a replacement, but its the inconvenience of being without it for  a week.

I have a tap on my 30fter which I hardly use, but when I do is a pain. I wouldn't want a week with a tap. I'm going down the "smear" route.

I wonder what the dirt inside the old ones could be when we only put pure water through them. Perishing O rings maybe?  Also, I wonder If they are using a new batch of O rings in the new ones that aren't quite up to scratch. Perhaps the specs are slightly off compared to the original ones. If this is the case then no amount of re-greasing them will work for long as the build up of water pressure inside them when shut off will force the grease out.

I also wondered that, I assume its coming from between the tank and brush head, all the components between.

I have copper piping between the tank and reels, some stainless steel too. The reels are fairly new, in fact the whole set-up with fittings were all done last January so 19 months old ish.

I took all 3 univalves apart last night, the two old ones were filthy inside. I cleaned and greased them and they seem to be working much better now, time will tell though.

The new one still leaks, what a pain! Having a good look around it I couldn't see a reason for the leak.

Did you struggle to take yours apart. I had one leak, followed the video that was posted on here, but lost my temper with it in the end and just fitted a spare one ?

I was always under the impression that copper shouldn’t be used to put pure through ?? That’s what Ionic’s said 20 years ago anyway, don’t know if it’s a moth or not ??

Good point. There's a chemical reaction that happens in some central heating systems because of different metals in the system that causes black muck to build up if not treated properly I believe. That would probably explain why I've never seen this in mine as I use a trolley and all my connections are JGs.

I put copper in when I put the immersion in, to cope with the heat.

I think I'll take it all out and re-place with speedfit.

It'll be interesting to see if your univalves stay clean after you've done it
