Non return tap connector

I want to connect my hot and cold outdoor taps to one hose for washing the car etc .
As they dont have an inbuilt non return valve cani just use a hoselock type non return valve on both taps , then connect to hose via a splitter/ y branch without any further plumbing.
Also are they required on both taps,
or should I have to replace both taps with built in valves?

"I’ve read both previous responses and without a doubt, fitting a TMV is the sensible option. The Hozelock check valves are only single stage whereas a TMV has integrated double check valve which is much more suitable.

"Yes any pipe work going outside should be protected by a non return valve"

"Technically the outlets require a double check valve not a single check valve.
We would recommend you install a TMV inside your property to service an outside tap with built in double check valve.
The TMV will blend the hot and cold for you giving you a constant temperature at the tap."
