    Anyone have a tip for slowing down the water ejecting from the washing machine into the deep sink? It shoots so fast and powerful that water covers the utility room floor.

    Is there some kind of diffuser that can be put over the end? Right now it's like a fire hose!

    Or is there a way to actually slow the propulsion down?

    The washing machine is made to operate that way and you should not modify it in any way.

    The problem is the drain is partly restricted and needs to be mechanically cleaned to restore the drain to its proper drain flow.

    Is this an old stone/cement laundry tub?

    nope; drain flow is fine. The sink is not over filling. In fact, it's only when the sink fills up to about an 1" that there is enough water in it to stop itself from spraying out. The 1" or so acts as a buffer.

    Imagine trying to fill and empty buck with a garden hose set on jet spray. For the first few seconds half the water just bounces back and flies right out of the bucket (and into your face!). But after a bit enough water is in the bottom of the bucket that it stops spraying out and begins to fill.

    That's exactly what's happening with this sink. It shoots down hits the bottom and flies everywhere until enough water is in there to cushion it. I suppose i could put a sponge where it hits to soften the impact but it will probably get knocked out of the way. If I could diffuse the exit of the hose though, make it sort of rain into the sink, rather than the one powerful mega stream it is now...

    You might try cutting a leg from a pair of nylon hose and tying it over the end of the discharge hose. You can't do anything that will impede the flow. Is there a way you could plumb in a conventional standpipe? The drain and standpipe must be 2" to handle the flow.

    any flat object will stop the backsplash from getting out of the sink while the water is first piling up. Spongy stuff will stop some of it but not all. Your choice.

    works good

    I would also try to angle the hose better.
    If you angle the hose just right you will not loose a drop.

    For sinks sometimes pointing the laundry hose down will cause it to splash out to the sink walls instead of shooting out.

    That is what I would try, and that would also double as a lint filter to help keep non-organic stuff out of your septic tank, if you have one. But remember:

    So, you will have to "change legs" every couple of weeks or so. Then, take the used one outside and turn it inside-out and let it dry out so you can shake off the lint and put it back in service the next time you switch them.

    Sure you can... Sounds like there is no standpipe and that the hose from the washer is likely parallel to the basin. Your washer manual will indicate the maximum height of a an allowable standpipe. Raise the hose to that height and loop it before dumping into the basin. Every pump in the world is rated for a specific flow at a specified distance (height) from the head. You increase the distance from the head and you'll slow the flow... Simple physics! Likewise the lower the hose the faster it will evacuate. Don't go crazy with the height because at some point due to the atmospheric pressure and size of the pump motor, you wont be able to move any water at all and will likely burn the motor out. (This is why I said to look at your washer manual). This still may not fix your problem if you have drain issues, but FOR SURE will slow the flow to the basin.

    Here's an idea, just an idea.
    Diffuse the stream by adding a short length of 2" PVC with a non sanitary tee on the end and seal off the top end with maybe a bushing & mission clamp, then glue in 2 street 90's to direct the flow downward.
