Example diagnoses with Pippie

Built for the field

P-Supp is a web app for pressure washer technicians. Its AI assistant, Pippie, helps you troubleshoot pumps, burners, engines, unloaders, injectors and electrical faults, and can read the model and serial from a photo. Answers draw on a knowledge base of manufacturer manuals, including General Pump, AR, Comet and BE Power, with live web search as a fallback. Available in English and Spanish.

🔧

Know the answer before you leave the truck

Pippie walks you through the fault tree — on the drive to the job, not two hours in. No more guessing which part to bring.
📐

Nozzle, injector, multimeter — sized in 10 seconds

Type in GPM and PSI, get the right orifice. No more flipping through the Kärcher book with wet gloves on.
📸

Snap the pump casting, get the seal kit

Works on greasy, blurry, upside-down photos. Pulls the model + serial and tells you which kit to order — no 15-minute call to Cat Pumps.

Pressure washer problems Pippie helps you troubleshoot

💧

Pump won't build pressure, pulses or leaks

Low pressure at the gun, pulsing, a dripping weep hole or milky pump oil. Work through inlet supply, unloader, check valves and V-packing wear before you order parts.
🔥

Burner won't fire or locks out

Hot water units that light then lock out, cold water from a running burner, sooting coils. Check the cad cell, electrodes, fuel nozzle, thermostat and air band.
⚙️

Engine won't start, surges or vibrates

Stale fuel and varnished carburetor jets, wet plugs and weak spark, loose pulleys and slipping belts.
🧪

Injector not drawing chemical

Downstream injector check valves, the right low-pressure soap nozzle, the suction line and injector sizing.
⚡

Breaker or GFCI trips, motor won't run

Guided multimeter tests for outlet voltage, motor windings, capacitors and cad cells. Pippie won't walk you through bypassing a safety device.

FAQ

What equipment does P-Supp cover?

Hot and cold pressure washers, gas and electric. Engines (Honda, Kohler, Briggs). Pumps (General, Cat, AR, Comet, Hypro, Hotsy, Udor). Burners, unloaders, injectors, chemical systems. If it's in a service shop, Pippie covers it.

How accurate is Pippie?

Pippie checks a knowledge base of manufacturer manuals and parts breakdowns before it answers, and corrections our team makes to past answers are built into future ones. When the manuals don't cover your question, it runs a live web search. It's an AI assistant, so confirm part numbers and specs against the manual or data plate before you order.

What if Pippie doesn't have the answer?

Two fallbacks: (1) live web search across pressure-washer forums and manufacturer sites, (2) submit the question as a "tip" — the admin reviews it, adds the correct answer, and the next tech asking the same thing gets the verified answer instantly.

Can my techs use it in the field, offline?

In the field, yes. Offline, no — Pippie needs an internet connection, so your techs need cell signal or Wi-Fi. Add P-Supp to your phone's home screen and it opens like an app. Built for greasy hands, with large tap targets.

Is my diagnostic data private?

Your chats are saved to your account, and admins in your company can see the team's history. To answer, Pippie sends your messages to Anthropic's Claude AI, and the P-Supp team reviews answers to correct mistakes and improve Pippie. We don't sell your data, share it with advertisers, or use it for marketing to third parties. Full details are in our Privacy Policy, linked at the bottom of this page.

How does billing work?
