6 DIY Hacks: Drain Flap, Drill Dust Catcher and Rotating Sprinkler

This is the secret trick my grandpa never wanted to reveal.

One, small animals keep crawling into your house through the drain pipe.

Cut the end of the drain pipe at an angle.

Attach a rubber flap above the pipe opening.

Add a weighted plate at the bottom of the flap.

Water can push the flap open to drain. When there's no water, it closes automatically and seals the opening.

No more bugs or small animals getting inside.

Two, heat the latch to a high temperature, then press a plastic bottle cap onto it while it's still hot.

The leftover heat creates a matching groove that perfectly fits the lock ring shape.

Lock it and screw the bottle onto the cap.

Rainwater can't get inside. It won't rust or get stuck even after years of use.

Three, drill a centered hole in the bottom of a plastic bucket.

Attach it to the front of a drill. The drill bit passes through the hole with an extra hole saw attached.

When drilling into ceilings, the plastic bucket catches the falling dust.

Four, cut off the top half of a detergent bottle cap, then cut new external threads around the bottle opening.

Soften the drain pipe with high heat, allowing the threaded cap to fit onto the pipe easily.

Cut a piece of rubber as a sealing ring, and you've made a deodorizing sealed connector.

Five, after fitting the pipe into the connector, heat the pipe and press it to create a sealed flared edge.

Attach a T-joint at the end. Install capped pipe fittings on both sides.

Drill small holes along the pipe. The water spray creates pushing force, making it rotate automatically and evenly water a large area.

Six, don't throw away old hinges. Cut sawtooth grooves on one side.

Fix it onto a support piece, and it becomes a simple self-locking anti-slip clamp.

It can easily control rope tension.
