Cheapest way to pump washing machine waste

I need to move a washing machine in the garage. Unfortuantly there is no suitable waste. The waste water will therefore need to be pumped up vertically to the ceiling, across the garage to the opposite corner where is can discharge into a drain.

Has anyone done this? What is the cheapest way to acheive this?

There's a Sani-something that will do this

Buckets.

Might be worth experimenting with how high the washing machine's own pump will handle pumping.

If that won't hack it, I would consider an external pump, driven from the machine's pump wiring (possibly via a relay, depending on how the pump supply is switched by the machine).

My dishwasher manages to pump it's waste much of the way around my kitchin. I coupled it's own hose (no air break) to solvent welded PVC 22mm overflow pipework which runs under the units, and rises up in the sink unit where it opens into the sink trap. This has worked fine for 7 years. No additional pump was required.

I would avoid long runs of concertina hose though. In the case of a long unvented pipe run, keep as much of the pipework as low as possible, to reduce the amount of water which runs back when the pump switches off.

I did that whilst refitting the kitchen! Moved the old sink unit into the middle of the room with a giant bucket under the sink waste, and a long washing machine fill hose coupling the movable sink unit to the supply. It was very handy to still have a working sink, which could be pushed around the room as you were working in different areas. The diswasher was still installed in the old unit under the draining board, and that emptied out into the bucket too. Had to remember to empty the bucket before starting the dishwasher though!

Sounds great until the Sani-whatsit fails and the garage floods because the washing machine doesn't know what's happened.

Redecorating the kitchen was a nightmare - re-fitting it must be awful!

Trying to use the appliances while doing either needs more powers of anything than I have :-(

Problem with that is backflow. The washing machine will fill back up with dirty water when the pump switches off, and depending on the washer it might never switch of or open the door due to the back pressure from the water on the pressure valve that senses the water level.

I wouldn't use the washers internal pump to pump for more than about 3 metres. Some will hack it, some will die rather soon.

Yes I thought about that.

However:

- It's waste water from a washing machine, not s*1t and vampire's teabags from a bog - ergo, there isn't the same jamming potential.

- It's in a garage and the consequences of a small flood may not be that significant.

If overflowing is a concern, then there are models from manufacturers such as Grundfos which do have overflow protection.

Hmm, well my wife manages to jam the washer pump every year or so by forgetting about pins, pens and other items in the clothes.

Mmm, but that's the washer pump.

Indeed, but it indicates that material that can jam a pump can enter a washing machine. There's no guarantee that all such material will jam the washer pump and it seems entirely possible that some. by chance, will bypass the washing machine impeller and jam the next pump in the chain.

So if that's a concern, get a pump with overflow protection mechanism.

i.e. not a Saniflow.

Which is why I mentioned Grundfos who have models that do, if one is concerned about any of these issues.

mechanism.

Drain m/c into a sump (maybe a c/h header tank) buried outside the garage so rim is flush with ground level. Have a sump pump of the type that has a float valve pumping the waste to your remote drain. If pump fails soapy water goes into garden and is not a disaster as it would be inside the garage.

Beat me to it. My idea similar. Drain into 45 gal drum. (cannot overflow on single wash) Use sump pump and hose to transfer to drain. Less than 50 quid for everything.

Do try to remember what you type.
