That's exactly what we asked from EBH and we were told the same, lucky I did not go ahead with them either because after handover I bought a y adaptor with a bidat stainless steel pack from Masters which cost me $20 I guess and installed it by myself I 20 minutes. Been using them from last 1.5 years with no issues.
Hi Hassanbegg
Is it possible to show me a picture of how you installed the Y adaptor? So I can get an idea of it....
thank you all...
