Fitting instructions for a Flomasta pump

Here you go Flomasta Pump

 

Doesn't work.

 

Really?! Works for me

 

Just takes me to google search page.

 

What's the issue wrighty.
Undo the nuts on the old one, slide it out, slide the new one in, tighten up, job done.

Oh, better get the water off first though.
Need lots of towels.
May not be able to get those big nuts undone without a 54mm spanner.
Make sure you get the flow direction arrow the right way round...
Nothing to it.

Call in a pro

Seriously, if you can shift the 54mm nuts the job should be a breeze. If not, drain down, fit new pump valves with the new pump
Good luck
