Perhaps the replacement was not done correctly.

Doyou know your water pressure?

Is this DIY?

i don’t know the water pressure, the landlords maintenance man did it. The other toilet done at the same time is working fine.

Time to get the maintenance man back. There’s not enough info here to diagnose what’s going on.

One way to prove that it is still leaking is to drop a few drops in the tank of the toilet. If the bowl water turns that color without flushing, then it is slowly leaking from the tank into the bowl. Do that test for the handyman if he balks at redoing things.

Perhaps the repair was not done correctly. It may be more productive to have the maintenance person review the work, vs asking on the internet?

Do not put dye in your toilet if you know it is leaking. Don’t use dye unless it is a tablet sold for testing leaks, you might stain your toilet.

Nancy, have you ever done the dye test, if so, with what ?

Haha was hoping it might be something I could dig into. Sadly the landlord forgets or doesn’t listen when I call in repair requests and getting my male housemate to call in is worse then pulling teeth. Thanks all

Food coloring, sorry I used the wrong word when I said dye! Yes, I used it just recently on a silent leak we suspected we had. It was leaking!

Keep calling and emailing the landlord. One time is not enough if you don't get results. Call every day until it is fixed. It is probably a very easy fix, and the maintenance person just didn't notice that something wasn't adjusted quite right. Post a picture of the inside of the tank for suggestions.

Is the flapper seated properly? Was the flush valve seal replaced? Have you called the landlord yet?

No idea, dont know what a flush value is, and no its up to my housemate to talk to them.
