Does anyone fit these internally for outside tap installation? Instead of an isolation valve and a separate double check valve.

Thanks means 2 less compression joints on an outside tap installation. I don't think many merchants stock them ? Haven't asked yet but just seem online

The isolation is usually ok in these?. Have been to some probably cheap filling loops that leak from the on/off lever when used.

The ones I use haven’t had a problem but it’s like anything needs to be used / operated 6 monthly etc
