Upgrade guide

Upgrade your shower in 10 minutes

No plumber, no special tools. Here's exactly how to swap a shower head, hose or rail — and how to pick the right one.

Check your fitting

Almost all domestic showers use a standard G1/2 (1/2") thread. Unscrew your old head by hand and look at the connector — if it's the common size, your Imph part will fit.

Remove the old part

Turn the old head or hose anticlockwise. If it's stiff, grip with a cloth for extra purchase. Clean any old tape or grime off the thread.

Add the washer or tape

Drop in the supplied rubber washer, or wrap a few turns of PTFE tape clockwise around the thread for a drip-free seal.

Fit your Imph upgrade

Screw the new part on by hand until snug — no tools, no overtightening. Hand-tight is enough.

Run the water

Turn it on and check for leaks at the joint. A quick extra quarter-turn usually fixes any weep. That's it — enjoy.

Pro tips

Hand-tight is enough — overtightening can crack plastic threads.
Wrap PTFE tape in the direction the part screws on, so it doesn't unravel.
Keep the old washer as a spare.
