    We just installed a Grohe Alira kitchen faucet with retractable handspray. Everything went smoothly at first, so simple compared to other kitchen faucets. However every time we turn the water on, the handspray unit shoots off the hose. It also comes off when we pull on it to use the spray feature. The instruction diagram is a bit crytic, and we can't figure out if a part is missing. According to the instructions, the handspray unit should just push on to the hose, with nothing but the tension from the washer holding it on. I don't think our water pressure is excessive. Anyone else installed one of these?

    Thanks for any advice,

    hose

    Water tension pushes things apart, it does not hold them together. There should be some sort of clip, or other mechanism, to hold it together.

    Does the nub the handle fits on have a depressed notch? Can you pull the bottom of the handspray out a little from the rest of it? You may need to pull that ring while inserting it into the hose to allow the lock ring to retract and allow it to fully seat on the hose.

    We've tugged on everything, and it seems the handspray just slips on to the hose. There is a rubber o-ring on the hose that provides the only resistance. Although the drawings for installation are extensive, this is the extent of the written instruction for this portion of assembly: "Connect the handspray (C) without using any additional seals, see fig. (4)". Looking at the figure, it does seem like something is missing from the end of the hose, perhaps a sheath that goes over the o-ring. However this is not indicated as an individual part on the dimensional drawing.

    It's going to go back in the box for refund. Thanks for the feedback,

    It's been my experience with that company that they are very well made. A call to them or the dealer should sort this out quickly. The instruction/installation sheet typically has little text and okay drawings. It looks like there is some sort of piece between the hose and the handle...can't tell from the exploded drawing what it is. Not sure if their on-line drawing is better or worse than what came in the box. http://www.grohecatalog.com/product...&prodno=99 999&prodtype=Chrome pull-out spray

    You are definately missing a part or you have a broken part.

    Problem solved

    Grohe replied to my e-mail within 2 hours. Here is the reply, for future reference:
    "The spray head is attached by threading the hose on to the head.
    In the diagram below it shows that the hose has a threaded collar, this is marked A in the diagram, the head is marked C
    The hose with the brass nipple and oring is pushed into the head and than the collar is threaded up onto the head.

    Note: sometimes the threaded collar is hide in the arm of the faucet.
    If you look into the arm you will see threads, you should be able to pull the collar out with your fingers."

    Actually the collar required quite some effort with tools to extract, but that solved the problem.

    Grohe fan once again

    I guess one of our problems was that you did not tell us your spout had threads on it and you didn't know what to screw it into. You implied that the spout was a smooth surface that slid into the hose end. You also did not tell us that you never pulled the hose out. We assumed your faucet had a new type of connection, rather than the standard one used on the majority of those faucets.
