Plumbing in a new washing machine

[recom273]

I'm after a little advice, regarding Asian top loading washing machines.

 

After purchasing a new Hitatchi, SF-150XWV, I checked the instruction manual, from what I understand it has a gravity drain and the waste pipe flows into a drainage channel.

 

Quite different from a western machine. I don't have a drainage channel, the "plumber" would only knock a hole above a concrete sill, and push the drain out into some waste land at the rear of my house. The sill is 9cm high.

 

The manual suggests the pipe should run no higher than 10cm high, that would leave a very short fixed downward drain about 20-30cm above the max drain height, I'm sure this would be under the height of the drum. What are my options, in this rented house, I can't dig drains, I can't break through the sill.

 

Sorry if the post seems garbled, I'm really confused.

Unfortunately a gravity drain is exactly that !! There is no pump to push the water out and therefore limits your options for draining.
Normally you will have a " concertina " drainage pipe that will allow the water to flow into the waste water drain together with water from your sink.
My machine is outside, under a covered area, at the back of the house and my temporary solution is to tape a length of pvc pipe onto the supplied pipe so water can flow into a drain cover outside. Not ideal, but eventually I can fit a submerged pipe to resolve.

Your situation is difficult as without seeing your set up it's hard to offer advice.

Is there no where low enough with access to outside where you can run a pvc pipe ?

Thanks, I was under no illusion of the gravity drain. It's a bit late now, but are all these top loaders gravity drain.

So, if the manual says raise the pipe no higher the sill is at 9cm, I think the exit point from the drum is 12-13cm. I think I safely do as you have done and run a temporary horizontal pipe. And in the long run, the only option is to form a concrete plinth around the 10cm high drain pipe and bury a u-trap within the plinth

What's a reliable way of fixing the corrugated drain to a length of blue PVC.

Reliable way ? , not sure, I just taped it together with a piece of pipe I had left from another job. Mine is outside so not a big issue.

My suggestion would be take your corrugated pipe to Home Pro or somewhere similar and see what you can find. I know there are hose connectors ( for garden sprinkler systems ) that might work ?

You are over thinking? Raise the machine. Most front loaders come with a plastic "surround" that elevates the machine slightly.  So if you put a concrete block under each corner?  

 

PVC to washing machine outlet pipe. As long as the PVC is larger than the PVC and the PVC has enough slope, use a bend on the PVC bung it in and use duct tape. If you wish to be a bit more technical measure the corrugated pipe, the dimensions of PVC pipe are on the web. Buy one that fits and use duct tape.

I have an old Zanussi stand that will raise the machine 10cm. It is 60cm square but has preformed screw holes so can be made smaller.

Yes, you are right, I'm over thinking. Mine didn't come with a plinth. I'm not really down with a couple of cinder blocks, so getting a wooden plinth knocked up today, easy.

I will go an see if I can buy or make a waste trap in Watsadu, as there will be enough room. Come off that to a vertical, and like you say, throw the waste pipe in there, game over.

Cheers all.

Whilst you're there you should be able to pick up a "universal" plastic plinth too.

From what I have seen, all top loaders made in Thailand are gravity drain and all front loaders use a pump.

Plinth that is word I was looking for 

[VocalNeal]

Washer pipe to PVC. 

 

Have a look at the end of the washer pipe. It may have a rubber end that fits over a 1/2" PVC pipe?  OR...
