Instruction required for how to use plastic conduit

[Eccles60]

I plan to add some exterior lights using the usual 20mm (approx) plastic conduit but have some questions about the actual use of plastic conduit:

1. Presumably any joins should be secured via a solvent glue?

2. How is an outside bend around the edge of a brick wall achieved?

3. I need to get a couple of cables from inside a garage through a brick wall and into the conduit system. What is the best way of starting off a conduit system (I assume I use one of the circular boxes and drill a suitable entry in the rear) and how do I waterproof the cable entry into it?

4. I aim to use a couple of bulkhead lights - again, how do I waterproof the conduit entry?

5. I also aim to use a weatherproof switch but with outside conduit entering from the top - again, how do I ensure water tightness?

All help gratefully received.

Yes, the same type which is sold for PVC waste pipes.

2. How is an outside bend around the edge of a brick wall achieved?

(I assume I use one of the circular boxes and drill a suitable entry in the rear) and how do I waterproof the cable entry into it?

Silicone will do, alternatively fit another piece of conduit into the back of the box and drill a hole through the wall large enough to fit the conduit through.

4. I aim to use a couple of bulkhead lights ... I also aim to use a weatherproof switch but with outside conduit entering from the top

Buy lights / switches with 20mm entry holes (most will have them) and connect the conduit using these:
