For the past few months, my shower pressure will get very weak for 5-10 seconds, then when the pressure resumes, the water gets scalding hot for a few seconds. This happens every 1-2 minutes while taking a shower.
It went a whole week without this happening and I thought it had fixed itself but it is back to doing it again.
Maybe a coincidence: but I can hear the toilet running at random times throughout the day for a few seconds.
Any help with this would be greatly appreciated, thanks!
Yep, fix the leaky toilet. Most likely a leaky flapper valve allowing water out of the tank untill it signals the fill valve to refill. This refilling is causing a pressure drop. This will also fix the high water bill you will soon be seeing
