Toilet making pipes vibrate?


Hi, all. Need some help. I think there's a simple solution but I just don't know it. Please note I am a new homeowner and don't know the simplest of things about home repair but I am learning as I go.

I just had all my pipes (but not drains) redone in my house.

I am still having a problem with the upstairs toilet. I thought it was because of the pipes, but it must be the toilet. There are no issues with the sink.

2 - 3 minutes after I flush, after the tank is filled up the floor and pipes in the floor/wall vibrate. It's loud.

I played around w/ it last night and while it's vibrating if I lift the float arm, the vibrating stops. Based on this information, what part do I need to replace inside the toilet to make the vibrating stop?

Thanks.

What problem were you having before?

2 - 3 minutes after I flush, after the tank is filled up the floor and pipes in the floor/wall vibrate. It's loud.
Was this the reason you had all the pipes replaced?

I played around w/ it last night and while it's vibrating if I lift the float arm, the vibrating stops.
Does opening and closing ANY OTHER faucet in the house have this effect?

No, it doesn't. Before I had all the pipes redone (they were mixed galvanized, pvc and copper, now all copper), I had one guy tell me it was an air pocket and to open all the faucets and let them run then shut them off after a while starting furthest from the toilet (didn't work) or it was a rust pocket in the pipes (now I have new pipes).

It was also suggested it was the drain but considering it stops when I lift the arm, I think it's the toilet, as someone else suggested to me.

How about both are right?
Or the first guy's instructions didn't go quite far enough?
(the toilet fill valve has crud in it)

Try the second part of this method first...

Remove toilet valve caps by rotating 1/8 turn counterclockwise.
(on basic Fluidmaster 400A: lift arm first)
Hold a container over the uncapped valve and turn water supply on and off a few times to clear debris.
Replace top by engaging lugs and rotating 1/8 turn clockwise.

sounds like the fill valve in the turlet. if it's a fluidmaster brand fill valve, just replacing the little rubber disc in the top of the unit will likely fix it. no tools required, about a 5 minute job, and cost about 2 bucks. flush the line out while you're at it by putting a cup over the top of the fill valve (while it's apart) and turning it on for a few seconds.

Thanks for all the info, you all gave me some good tips.

End result, bent the float arm and that stopped the problem. I didn't think of this myself, of course. Boyfriend did it.

That's an older flush valve---a new one is only about $10--and is simple to install---if the problem happens again--just change the guts--

It is an old toilet! I will change it out at some point. Figured I'd try the easy fix first. TY!
