Simply Build It

Whether it does or not it won't work properly with unbalanced pressures between hot and cold.

You either need a separate cold feed from the CW storage tank so that hot and cold are at the same pressure OR fit a pressure reducing valve in the existing cold mains feed.

Alternatively you may have a combi boiler in which case both hot and cold will be at mains pressure anyway.

Hope that helps.
