Plumbing inspection camera for your phone

Most plumbing problems at home are within arm's reach: a slow sink, a drip inside the wall behind the shower, a damp patch under the cabinet. A waterproof camera on a 1 m cable shows you what's going on before you take anything apart.

Short answer

For the first meter of a drain, a sink trap, the space behind a toilet or a wall cavity around a pipe, a phone inspection camera with a waterproof tip is enough. Reach 360's tip steers around bends; Reach Duo's side camera reads pipe walls and joints. Both have 1 m (3.3 ft) cables, so they're not sewer cameras — for a main line, call a plumber with a sewer scope.

Jobs it's good for

  • Slow sinks and tubs. Look down the drain to see whether it's a hair clog near the top or something further down.
  • Under the sink. Check the back of the cabinet, the shut-off valves and the joints behind the trap without emptying everything out.
  • Inside the wall behind a shower or toilet. Through a small hole — or the gap behind a cover plate — look for a dripping joint, wet insulation or a stained stud.
  • Under floors and behind appliances. Through an access hatch or a vent, follow a pipe to where it's wet.
  • Vents and ducts. Look inside a dryer vent, an air duct or a bathroom fan outlet for blockages and debris.

What it can't do

  • It isn't a sewer camera. A 1 m cable reaches the first part of a drain, not the main line under the yard. For root intrusion, a collapsed pipe or a blockage far down the line, call a plumber with a sewer scope.
  • It doesn't clear clogs. It shows you what and where the blockage is, so you know whether a drain snake or a plumber is the next step.
  • It doesn't push through several tight bends. Both cables hold the shape you give them; they don't snake through a run of elbows like a plumber's cable.

How to check a slow drain

  1. Clear the opening. Take out the stopper or the strainer.
  2. Wipe the tip and connect the camera before you start feeding the cable.
  3. Feed it in slowly with the picture on the screen. Water and soap on the lens blur the view; pull back and wipe it if they do.
  4. Stop at any resistance. Don't push the cable through a bend it doesn't want to take.
  5. Clean it afterward. Wash the cable and wipe the tip with a disinfectant wipe, and let it dry before you put it away.

What you see, and what to do next

What you seeNext step
Hair or soap scum near the top of the drainClear it with a drain snake, or take off and clean the trap
Something that shouldn't be there, such as a toy or a capTake off the trap if you can reach it from there; otherwise call a plumber
A dripping joint or wet insulation inside a wallTurn off the water to that fixture, take a screenshot and call a plumber
A cracked or corroded pipeTake a screenshot and call a plumber
Nothing in the first 3 ft (1 m), but the drain is still slowThe blockage is further down, so it's a job for a plumber's sewer camera

Find the spot first, then look inside

Before you cut a hole, narrow it down from the outside. A thermal camera shows a wet patch as a cooler area and a hot-water pipe as a warm line; a pinless moisture meter confirms the wall is wet. Then one small hole is enough for the scope — see how to find a water leak behind a wall. For a wet wall behind the bathroom, see how to check a shower leak. Only need a camera for one job? Here's when renting makes sense.

Questions

Can I use it in water?

Yes. Both scopes are rated IP67 at the camera end, so a wet drain, a trap or a tank is fine.

Can it inspect a sewer line?

No. The cable is 1 m (3.3 ft) — enough for the first part of a drain, not a main line. That needs a plumber's sewer camera.

Will it get through a P-trap?

It can look into the trap and the pipe either side of it, but a stiff cable doesn't reliably snake through tight bends.

Which is better for finding a leak inside a wall?

Reach 360. Inside a cavity the drip is usually above or below the hole, and a bending tip can look along the cavity.

What is the camera called that plumbers use?

Usually a sewer camera, also called a sewer scope or a drain camera. It has a long pushrod cable made to travel down a main line, which a 1 m (3.3 ft) phone scope can't do.

Can you rent a sewer inspection camera?

Some tool rental desks rent them, but stock varies from store to store, so call first. Reading the picture takes some practice, so hiring a plumber with their own camera can be simpler.

Can I return it?

Yes, within 30 days of delivery if it's unused and in its original packaging; change-of-mind returns go back to the supplier's warehouse in China and you pay the return postage. If it doesn't work with a phone we list as compatible, we refund you in full, including return shipping.
