Boiler pressure
Falling pressure and cold radiator tops are a common combi pairing — Pipewise splits the safe checks from the boiler work.
AI plumbing & heating diagnosis
Know what's wrong.And what it'll cost.

Pipewise · diagnosis workspace live
Pipewise gives informational diagnosis and planning guidance only. It is not licensed plumbing, heating or gas engineering advice, and is not a substitute for a qualified professional. Gas and electrical work must be carried out by a registered engineer.
How it works
Describe. Plan. Picture.
Three steps from a worried question to a clear, costed plan you can hand to a professional. No jargon, no pressure to book anything.

A plumber's judgement, made visual.

Describe it in plain words
Say what's wrong or what you're planning. Pipewise returns a structured diagnosis: likely causes with confidence, an urgency rating, and a clear DIY-versus-professional split.
02 · Plan
See the layout and the heating
Get an illustrative fixture layout, a before/after visual and a heating & radiator plan with hot/cold zones — enough to align on direction before you get quotes.
03 · Understand
Learn how the system works
An illustrative system schematic explains your combi or system boiler and pipe runs — a teaching diagram, so you know what a plumber is talking about.

On Mains, generate a short renovation walkthrough in 16:9 and 9:16 — one to keep, one to share — plus a Project Brief PDF to take to your tradesperson.

Field notes
Real problems, sorted into what's safe and what's not.
Radiator balancing
Cold tops mean trapped air; a cold radiator with hot pipes means balancing. Different fixes, clearly separated.
Safety first
Gas and electrical work is for the pros.
Gas work — boilers, gas fires, flues — must be done by a Gas Safe registered engineer, or the legal equivalent in your country. Electrical work must be done by a qualified electrician. Pipewise output is informational and must never be used as the basis for unqualified gas or electrical work.
If you smell gas, suspect a leak, hear a carbon monoxide alarm, or see a boiler smoking or behaving abnormally: stop, open windows, leave the property and call your local gas emergency line and a registered engineer. Do not rely on this tool in an emergency.
