My main bathroom toilet is completely clogged and won't flush. I've tried plunging it, but it's not budging, and I'm worried about water backing up into the bathroom floor if I try to flush again.

Use a plumber's snake, high-pressure water hose, or even carefully disassembling sections of the downspout to remove any obstructions.

Professionally adjust the slope of the gutters to ensure proper water drainage towards the downspouts.

Invest in high-quality gutter guards designed to prevent leaves and debris from entering the gutter system.

Inspect existing gutter guards for clogs and clean them thoroughly. If they are damaged or ineffective, consider replacing them with a more robust system.

Ensure downspouts are clear of blockages by using a plumber's snake or flushing them with water from a hose.

Safely remove all accumulated leaves and debris from the gutters using a ladder and appropriate tools like a trowel or scoop.

Open hot water faucets throughout the house to allow any trapped air to escape. This is often done after maintenance or if the system has been drained.

Inspect the water heater and surrounding pipes for any signs of leaks. Tighten connections if necessary.

If the scale is severe or the elements are damaged, they may need to be replaced.

Carefully remove and clean the heating elements to remove any scale buildup. This may require specialized descaling solutions.
