puer pro in-line filter cartridge

[sengaul]

Hi everyone,

has anyone ever come across these? a friend of mine has asked me to install one along with a three way tap. I have some basic plumbing knowledge, but have never installed one before, they have no documentation for it but from what I can find out from PUREPRO website it is usually installed on ice making machines and coffee machines.....no mention of kitchen taps? it looks pretty straight forward to install but i just want to be sure that it can be used on a kitchen tap, and would i need to add a check valve downstream of the filter? One last thing....... what would be a fair price to charge for this??

Thanks for any help and advice in advance. (hope I have posted in the right forum....new to the site)
