Frequently Asked Questions
Get answers to common questions about T300si support, spare parts, and replacement options.
My T300si is discontinued - what should I replace it with?
The recommended premium replacement is the Triton ENVi® range, which offers next‑generation digital controls, multiple kit options, and user‑friendly features like personalised profiles and usage feedback. For customers who want a stylish but less like‑for‑like swap, the Amala and ENlight® electric showers are available, though these require more installation changes.Is upgrading from a T300si to an ENVi® easy?
Yes. A retro‑fit back plate is available to make the T300si‑to‑ENVi® swap straightforward and tidy — helping cover existing fixings and reducing the need for retiling.If your T300si was installed with a through‑the‑ceiling riser rail, the ENVi® Ceiling‑Fed Kit is the most compatible upgrade. ENVi® supports a ceiling‑fed configuration just like the T300si, making installation simpler. If your T300si was wall‑fed, choose the ENVi® Wall‑Fed (Inline / Back‑to‑Wall) Kit, which accommodates wall entry points.Why is ENVi® considered the premium upgrade option?
ENVi® provides significant improvements over the T300si, including:
- Full‑colour digital display with real‑time water & energy feedback
