Ian,
I know some of the other companies have been difficult in the past about covering the Lamb Ametek motors , particularly replacement ones fitted by us cc's.
The reason is that they blame the cc's for foam in the tank etc and to be fair this has probably been the case in a few instances.
However I cannot see any of these diclaimers standing up in court because goods have to be fit for the purpose.
Steve,
The power of the consumer is always the best tool for raising standards and these forums enhance that power

e.g I now know a lot more suppliers of motors , local and at good prices so I don't feel I need to put up with shoddy service, just because I bought from a particular supplier in th e first place.
Cheers,
Doug
