I've already done that.
ok i read it as you had cleaned it, sorry. did you already remove the new one and check to see if any debris is stuck in it by flushing it out? is the image attached the diverter that you replaced?
That is the correct Diverter and there is no debris.
I tried the Danco brand first, that was far too loose and made the sink vibrate as well. I went to a plumbing supply and I assume they gave me the Delta brand but there was no packaging. I haven't used any lubricant.
if there was no packaging i doubt it was the delta brand. i do know from experience the danco brand replacement parts are not machined very well and don't always work. can you call the supply you got it from and find out if that was the delta one?
They're closed now but I will try tomorrow. Thanks for the responses.
I figured it out and it's not the valve. I shouldn't have had to replace it at all. The problem was with the dang sprayer and a plastic washer that the instrustions tell you to have on there that was messing with the seal and so I guess the pressure as well.
It says if I rate you ok or above you get credit and no offense but you didn't answer the problem. Thanks for the attempt but I ended up figuring it out by continuing to mess with things other than the diverter valve.
