What are my options here - Replacing Shower Pump

[uptoyou]

Hi all,
Need to replace my shower pump but have run into a small issue:

Pipes and fittings are very close to fitting. I can possibly try and get away with the two outlets as you see pictured (two at the rear, not push-fit connected yet), although it will be a little high.
This leaves me with needing to by two different hoses to fit the inlets and there are no valves fitted to allow me to isolate the water suplpy.
Are there any options open to me which don't require isolating the hot and cold water as I can't find the hot isolation valve. Can I isolate the cold water in the left using those two large shut-off valve?
Pictures to hopefully provide some more clarity:




Appreciate any advice!

Bung the outlets of the cold water storage cistern ,and drain off via hot taps ,and any cold taps that are fed from the cistern ( if any),and the shower.
The two valves on the cistern should isolate hot and cold , unfortunately those old gate valves often don't fully close,but you could try ,you may be lucky !

Awesome, thanks! If those valves don't close, when you say bung the outlets - do you mean literally bung something in the outlet inside the bottom of the cold water storage? That would be challenging, not sure how I would go about that?

As above ,or anything similiar, bottle stopper / cork etc.
If all else fails close the supply to loft tank ,tie up the ball valve if no isolator ,and drain the loft tank via taps / shower.
