My parents have just ordered a new Bosch washing machine, I've had a read of the online manual and it stated that the nozzle should be a minimum height of 60cm from ground level for adequate drainage ( presumably ) . I have measured the current nozzle height ( plumbing under the sink ) and it is 50cm from floor level, I have attempted to purchase an angled nozzle to bring the height up but am not having much success. I need 40mm diameter and all I can find are the standard nozzles which won't give me increased height. Any suggestions please of where I can get a 40mm angled nozzle and if 50cm from floor drainage would cause problems thanks

Bosch washing machine drain connection height query
- The problem
- A new Bosch washing machine manual stated the drain nozzle/standpipe should be at least 60cm above floor level, but the existing under-sink waste connection measured about 50cm. The concern was whether this lower height would cause draining problems and whether an angled 40mm nozzle was needed to raise it.
- Likely cause
- The accepted reply suggested the main risk was siphoning if the drain hose is inserted too far into the standpipe, rather than the 50cm height alone necessarily causing a fault.
- What fixed it
- The advised action was not to alter the plumbing immediately. Fit the drain hose through the supplied shepherd’s crook/hook and only leave about 5 to 6 inches of hose protruding to enter the standpipe, so it cannot be pushed in too far and siphon water out. Only consider extending the pipe if problems actually occur.
- Checks to try
- Measured existing waste/nozzle height at 50cm from floor level
- Checked new Bosch washing machine manual stating minimum 60cm waste height
- Ensure the drain hose is not pushed too far down the standpipe
- Use the supplied shepherd’s crook/hook on the drain hose
- Parts or tools mentioned
- Shepherd’s crook/hook supplied with the washing machine

Hello Wayne. I wouldn't worry about it. Just make sure the drain hose isn't pushed too far down and it will probably work OK. The drain hose needs to be pushed through the shepherds crook that should come with the machine. You need about 5 or 6 inches of the end of the drain hose at most to stick out from the hook. Just enough to push into the standpipe so it won't fall out. If you push it too far into the standpipe water will siphon out.
If you have problems you might have to extend the pipe but if your previous washing machine worked ok any new when ought to.
Read this article where it's headed, "siphoning water" carefully to understand the issue Washing machine fills and drains at same time - the shepherds hook (or crook) is also mentioned.
