I need to order a spare part?

I have installed in my W.C a Mac Dee mechanism of the following model:
METRO
3-PART
SYPHON RANGE

I need to order the diaphragm of the syphon, and I can send a picture of the said diaphragm which is damaged so that you may supply the right part, therefore please give me your e-mail address.

I will also supply to you the address in England (in Bedford) to which you can deliver a new diaphragm, can you tell me how quickly you can send a new one and how much it will cost?

For sake of information, the address is:

Lecico PLC
Unit 2E
Viking Industrial Estate
Hudson Road
Bedford
MK41 OQB

I look forward to receive your reply.

Best regards
