I'm having trouble tightening the pipe union nuts on some new bath taps I've fitted at my mum's house. I got everything out OK, and (because the previous plumber had put the hot tap on the right rather than the left) I used flexible pipes to connect the taps to the pipes so I could cross them over to put the hot on the left. I chose push fit connectors for this part because of the limited access and those connections went on with out a hitch.
In case I've got the terminology wrong the above is a diagram of a typical tap installation with the offending nut highlighted.
The union nuts at the tap are causing me problems because of the restricted access and limited space. I can't get enough purchase to tighten them using any of the wrenches I already own.
Do I need a "Jaw dropper plumbing wrench":
The description reads:
For tightening taps without isolating the water supply. Adjustable jaws allow for access to both the pipe union nut and the tap back nut with the same spanner.
Or a "Telescopic basin wrench":
I think that it is the jaw dropper wrench but I've never heard of those before. I have heard of a basin wrench but always assumed that they were for tightening or loosening the nuts on the plug hole. So before I buy something I really only need for one job I ought to make sure I get the right tool.
