We're installing the drain plumbing for a newly installed tub, and the drain shoe overshoots the tub drain hole. The tub has been mortared in place and can no longer be moved:
A joist limits how far back the overflow tee can be positioned, and as you can see in the picture, the connectors of the shoe and the tee are already flush against each other.
I only need the shoe drain to move about 1/2" towards the joist. Would it be acceptable to simply trim the connectors of the shoe and tee by 1/4" each to get everything to move back to where I need it?
For reference, the standard depth of the connectors on 1.5" PVC fittings is 3/4". Is there a minimum connection depth that I need to keep to ensure a leakproof connection?
