Worn toilet flapper causing a running tank
The flapper has lost its seal, so water trickles from the tank into the bowl and the fill valve keeps topping it up. Replacing the flapper usually solves it.

Leo, what filter does my furnace use?
Your furnace takes a 16 × 25 × 1 pleated filter. You last changed it in March — it's due again next month.

And Leo knows when not to DIY it.
FixLeo separates how hard a repair is from how risky it is. Plenty of plumbing, heating, and electrical jobs are perfectly doable at home — and Leo will say so. When a job involves higher-risk electrical, gas, refrigerant, structural, or emergency conditions, Leo recommends a licensed professional instead.
Straightforward and low risk — go ahead with basic tools.
Doable with care — Leo flags the precautions before you start.
Call a licensed professional. Leo won't walk you into it.
Safety rating is separate from difficulty on every diagnosis.
