🛠️ HOW TO FIX IT PROPERLY
✔ 1. Remove foam and expose full wall opening

Remove all foam around the pipe to access the entire network.

✔ 2. Remove the entire cluster of fittings

The series of small angled connectors should be replaced with:

A proper vertical stack

Correct wye (Y) fittings or sweeping tees

Not sharp elbows.

✔ 3. Redesign the system layout

A proper design includes:

One main vertical pipe

Branch lines entering at 45° wye fittings, not 90° elbows

Correct slope: 2–3 cm per meter (¼″ per foot)

✔ 4. Install pipe clamps / supports

Every:

50–70 cm for horizontal drains

1–1.5 m for vertical stacks

✔ 5. Add an accessible cleanout

The top cap in your picture might be a cleanout, but its placement is bad.
It should be:

Straight, reachable

Not buried behind the wall

✔ 6. Seal wall openings using mortar, not foam

After pipes are solidly fixed, the wall should be sealed with:

Cement mortar
or

Plasterboard + insulation

NOT with expanding foam pressing on the pipes.

✔ 7. Ensure venting is correct

Drainage must be vented to avoid:

Siphoning

Gurgling

Slow drainage

🛠️ Proper Way to Fix It

Remove the Improvised Materials:

Cut away the foam and remove cable ties.

Clean both pipe ends thoroughly.

Check Compatibility:

Identify both pipe types (PVC, ABS, or cast iron).

If they’re different materials, use a proper transition coupling (e.g. a rubber Fernco coupling with hose clamps).

Install a Correct Fitting:

Use a PVC or ABS Y/T-fitting rated for drainage, matching pipe diameters.

Use solvent cement for PVC-to-PVC joints or rubber couplers for mixed materials.

Support the Pipe Properly:

Use pipe clamps or hangers instead of cable ties.

Ensure no stress or weight is on the joint.

Seal the Wall Opening:

After the pipe is secure, use non-expanding foam or cement mortar only to fill wall gaps — not to seal the pipe itself.
