    Copper to IPS valve

    I want to connect the copper Hot and Cold lines to a Thermostatic valve. The Thermostatic valve has three male IPS fittings. I will also need a couple of check valves; most I have seen are female IPS to female IPS. Ideally I'd like to use a union, so I can remove the valve if I have too, but...
