thanks everyone for your replies ,and yes I have asked for the pump back but they still looking for it I will let you know of the outcome
Well that rather sums up the intelligence of this "other plumber" and your customer....
I am guessing that every man and his brother knows that 99.9999999999% of goods have 12months manufactures warranty....
So you would keep hold of any item you think is dodgy to return it to the supplier for refund..
If "Still Looking For It"..
its either binned or chucked in the other plumbers van..
Or he's used it on another job!!!
But whichever way you look at it...
A pump even if it had been connected reveresed...
will still be a working pump....
Not a faulty or damaged pump!
So no need to change the pump again if you had replaced it less than 12months ago!
Write them a letter saying you are more than willing to look at the original pump you fitted
and if it proves to be faulty offer a appropriate refund for the defective parts..
(as you will get a refund from your supplier)
But without the original item for inspection you are unable to prove that this other plumber hadn't damaged the item you installed.
If the original item is not faulty and did only need reversing then the best you could offer is a good will payment of the labour for the time it would have cost to reverse the pump around.
In either option you need the original pump back in suitable packaging just as it was when you supplied it.
so you can evaluate what/if any refund is suitable.
Ask them to return the pump within five working days so the mater can be resolved promptly,
If no pump is returned then you will assume they are happy for the matter to stay as it is!
