so my univalve has been playing up, and today finally died .
so I put this tap on as quick make do for the day .
obviously its no good for use on upstairs, however I found it far more efficient on downstairs, and think I saved more water.
it much easier to use than tugging constantly.
I will give it a few more days to see how I get on, and may stick with it.
I think it was about £8 on ebay
