How do I connect my washing machine drain hose?

asdf

Hi, thank you in advance for answering my questions. 

First question: I have an open pipe that looks identical to the other under sink pipe, I assume that can be used for drainage and I can put the washing machine waste water pipe straight down with the U shaped bracket? Is there any way to test that is in fact a drain pipe?

I did some research and it also says I should attach the U bracket (included with the washing machine) to a wall so the pipe doesn’t move around when pumping out waste water. If that is indeed a drain pipe, the bracket will be too far from a wall (see picture) What is the best way to attach it?

I saw some images online and it said to connect it like this. Would that somewhat be similar in my case?

Final question: I require an extension hose which I’ve already bought. The rubber ends fit nice and snug so I assume I don’t need a hose clamp for the joining part of the pipes? And according to the manufacturer manual, it says I should install like this 

My drain pipe is nowhere near at least 60cm. Is that going to be an issue or will it be ok if I just put it down the pipe and I guess wrap the extra length around the perimeter of the cabinet? 

Any help and comments are very appreciated. I’ll attach some more photos below for more reference. 

I do have 2 spigots however they are hard to reach around to drill a hole into for the drainage. I’d much rather put the waste line down the pipe if that is a suitable drainage point. Thanks in advance

Welcome to the Bunnings Workshop community @asdf. It's wonderful to have you join us, and many thanks for your question about connecting a washing machine.

You should find this guide useful: How to connect a dishwasher. It's the same process for your washing machine.

I'm not entirely sure what that exposed pipe is, but if it is connected to your waste water it does not comply with plumbing codes. It needs to be capped off. Your hose must be connected to your sink's S-trap, which is shown in the above guide. I've circled the two outlets in the image below. Remove the cap from one of them and push your hose on, securing it with a pipe clamp. You shouldn't need to drill them.

I do not recommend you join two hoses as they will be under some pressure. Instead, I suggest you run the extension hose back to the machine. Remove the shorter hose and connect your extension hose directly to it. Hopefully, the extension hose is long enough to reach back to the trap. If it's not, you might need to purchase a longer extension hose. It's always best to run one hose as any joins are potential leak points. It's not a secure method to just push two hoses together, you'd need some type of joining barb between them and clamps.

The instructions you have are likely American, and it is not compliant here to simply push the hose down the open drain pipe.

Please let me know if you have any questions.
