Cutting and capping the existing left branch of the T will probably cause future problems as the flow direction from above is directed towards the capped side.
Chopping out the T and fitting a 90deg elbow will be awkward as the pipes will be too short, although a long radiused elbow may work
A pair of 45deg elbows would save messing around with inline couplers to regain an inch
Thanks so much, this makes total sense to a beginner like me. Much appreciated. If I don't have enough length with the pipe on the right for 2 x 45°s is there a way to remove the t piece and fit a 90° elbow?
If you were to cut the pipes close to the T, the removed left hand branch looks long enough to add between two 45s and extend as required to make up any shortness
