Electric shower leaking water from the unit itself (Triton & Mira)
⚠️ This needs a qualified professional
This fault involves gas or mains electrical work. Don't attempt a DIY repair — UK law requires gas work to be carried out by a Gas Safe registered engineer. Below is what to check and describe to them, not step-by-step repair instructions.
Water visibly leaking from the electric shower unit itself — not the hose or shower head, but the wall-mounted box — is a combination of water and mains electrics in the same fault, which makes this one of the clearest “stop and call someone” situations on this whole site.
⚠️ Stop using it immediately
Do not use the shower again until it’s been inspected. Switch it off at the pull-cord isolator switch and, if you’re able to safely do so, isolate the circuit at the consumer unit/fuse box as an extra precaution. Water finding its way into a unit that also houses mains electrical heating components is a genuine safety risk, not just a nuisance leak.
What’s worth noting before you call someone
- Note roughly where on the unit the water is coming from (top, bottom, a specific seam or fitting) — this helps whoever attends narrow down whether it’s a water-side seal or something more serious.
- Note whether it leaks constantly, only when the shower is running, or only right after you switch it on/off — timing can point to different causes.
- Don’t attempt to open the unit casing or tighten anything yourself.
Who to call
This needs a qualified electrician, and given the fixed bathroom electrical installation involved, any repair falls under UK Part P building regulations — not a plumber alone, and not a DIY job under any circumstances.
