Double check valves ??

[townfanjon]

Guys , I look after a large dentist and the waterboard have done assessment / check this afternoon and want some ECED valves fitting , I have never heard of them but pretty sure they are just double check valves, does anybody know if they are a specific type of valve or just the usual double check valves.
Cheers in advance

Two types of valves, EC or ED, both forms of double check valves

Cheers Craig looks like the manager has given me the wrong info , she said he wants eced valves not ec or ed valves lol wondered why I had never heard of them .

TBH fit ec covers both bases

One is just testable that it’s functioning

Not for a steam steriliser is it?

Not sure pal , the manager just has a list of stuff he wants doing , going down in the next few days .
One remark made me laugh , one of the toilets has a dudley turbomaster syphon in it ( I fitted it ), no over flow on the bottom of the cistern and he said the place could flood if the ball valve failed
