Supplied with faulty immersion - what to do?

[quality]

Its a massive pain. I had a bloody 6 month old kitchen tap cause me issues recently by leaking, its incredibly annoying. It always seems to happen when I am rushed off my feet, ended up having to free up some time so remove the faulty tap take it back to the suppliers and get another one and then go back and fit it. All for free, its just the joys of working for yourself and running a business. If you are adding 10-20% on all the materials you supply, that covers the call backs and should still leave you with profit, that's how I look at it anyway.

Ive not read all the posts. But thats why I put 50% on everything I supply. If Im to expensive then I don't want the job
