Hi @thilaksr,

Thank you for your question and welcome to the Bunnings Workshop community.

Unfortunately, as plumbing is a licenced and regulated profession, this is not something I can advise on.

I'd suggest contacting a plumber to install a suitable isolation valve that will work with your system.

Let me know if you have any further questions.
