    So a couple of days ago i worked with another window cleaner from his van on a big job. Water use wasnt a problem so he had the de set at 65 and flow at 75 and the pressure of the water coming out was amazing. I could work so much quicker and rinsing was a dream.
    so I tried to get my system which is basically identical to his to run the same but just cant get it even near as good, even if i pump the settings higher than his.

    But one thing I noticed and often have in the past is a kind of rattling noise when the pump runs which i always thought was coming from the pump itself. However today i realized it is actually coming from the top of the resin bottle.
    Im sure in the past its been a lot worse when there has been air in the system. So could there be air trapped inside the bottle? Or some other problem with it?
    The resin bottle is one of those dumpy ones.

    Any help appreciated thanks

    It's more likely air is in the system going into the di tank. Have you done a test by disconecting the di and wacking the pump on full pelt to see if it flows well and consitant?

    I have done that in the past usually when I have run out of water the day before as it always then has air in it. It will be really bad then in fact the bottle visibly vibrates on those occasions. I've just always felt that there is something not quite right with the way my system works. Its the best is been but just opened my eyes a bit too what it should be like when I was using my friends last week.

    What type of tank are you using flat or upright?

    Does the DI leak? How is the DI held in place, not a bracket or anything rattling is it? Is it the riser tube rattling? Can't think of any other questions ATM.

    I would suspect it is the hose coming from the outlet of the pump that is vibrating with trapped air in it not the di head itself. The tone of the pump is noticeably different and vibrates much more too when air is not bled from the system properly.

    I suspect your pump strainer needs cleaning. If this is caked up it will prevent a high flow & puts a higher load on the pump as it struggles to pull enough water through the restriction of the strainer. This also can make the pump kind of rattle.

    Hi guys thanks for the replies. I have checked the strainer and it is totally clean. The Di is not clamped down at all it doesn't slide around at all. I had a good listen smurf and actually I think the vibration is coming from the hoselock going into the Di. It is one of the aquastop ones that shut off if it is disconnected and I think it's the little plastic bit inside that closes it off that is vibrating. Is it possible that this is restricting the flow a bit? I do remember reading someone saying they never use the aquastop ones as they had trouble with them.
    On the out side of the Di head I have not got a hoselock as it was forever popping off for some reason.
