Would it not make more sense to leave the black isolator in place? Then you can use the lever to better regulate the flow just leave the penny valve isolator open and turn off the black one, good idea to leave in place for future filling

The black isolator should've been installed in place of the isolation valve on pipe 4 in the first place, so the OP's no choice but to remove it from the loop because the loop hose won't connect otherwise. The installer shouldn't have fitted that end cap on the non-return valve either and instead just used a the hand screw type that's on pipe 4. The installer has made life difficult for their customer.

Thanks for the continued help. Right now I just need to know if that Screwfix tool will help me get the brass cap off pipe 5.
Cheers.

Should do. You can then replace it with a cap such as this.

Did you say you had an adjustable spanner, GQ? If so, that will fit - slip each jaw along to touch two ridges on either side of that nut. Two ridges = a nut 'flat'. Sort of...

But, a plumber's wrench is always a good tool to have in yer 'box.

Have already ordered that item from Screwfix, collecting at 6pm

You can never have too many :-)

I was thinking more like one of these: https://www.screwfix.com/p/magnusson-water-pump-pliers-12-305mm/3684v which I find myself reaching for for almost every similar job. The 'locking' type (used to be 'Mole wrench') is great for specific jobs, but the fact it locks makes it fiddlier to use if all you want is a quick wrench (ooh-er, missus).

But they all deserve a place in yer tool box

I've only bought them to do this one job!
You sure the ones I already paid for will do?

Yes, it'll do fine.

But so will the adjustable spanner you already have!
