An AI sales agent's home pressure system order, checked before it goes out

An AI sales agent prepares an order for a Davey HM Series home pressure system (Torrium2 models HM60-06T to HM160-19T, or the pressure-switch models HM270-19P and HM270-25P) for a fictional rural property services contractor: the model, the flow and pressure the job needs, the water, the power supply and any tank. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of what the public Davey datasheets say and returns a verdict, every reason and the figures it computed. The customer is fictional.

Scope: Davey HM Series pressure systems only (Torrium2 models HM60-06T to HM160-19T; pressure-switch models HM270-19P and HM270-25P): duty, water, power supply, controller features and tank pre-charge. See everything this validator covers

This validator models orders for the ten Davey HM Series home pressure systems named above, based on the public Davey datasheets "HM Series Home Pressure Systems" and "HM Series Horizontal Multistage Pumps", not just the scenarios shown below.

  • Duty — the continuous flow limit of the controller type (200 litres a minute for Torrium2 models, 430 for the pressure-switch models), the maximum pump pressure of each model, and a nominal flow and pressure for each model beyond which a person checks the performance curve.
  • Water and site — maximum water temperature (65 C for Torrium2 models, 95 C for pressure-switch models), maximum inlet pressure of 600 kPa, maximum ambient temperature of 50 C and sand or abrasives up to 40 g per cubic metre.
  • Power supply — 50 Hz; single phase 230 V plus or minus 10 percent; three phase 415 V plus or minus 10 percent; the Torrium2 controller is single phase only and three-phase pressure-switch units are on request.
  • Controller and tank — loss of prime protection is listed for the Torrium2 models only; a tank added to the system must be set to the air pre-charge the datasheet gives for the model.
  • Statement — the maximum pump pressure the order states against the datasheet figure for the model.

Any order of these ten systems that touches these rules is in scope — not only the scenarios pictured here. Not covered: the performance curves themselves (the datasheet gives them as graphs), other Davey pumps and pool or irrigation products, suction lift, pipe sizing, tank sizing, prices (Davey does not publish list prices), delivery and installation.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Limits that differ by controller typeOnly with care
The flow, water temperature and phase limits differ between the Torrium2 and pressure-switch models. A rules-based CPQ can store the table, but it has to be kept in step and compared with every job.		The model is read together with the job, and every limit is computed on every call.
A feature that only some models haveOnly with care
Loss of prime protection is listed for the Torrium2 models only. Each is a product rule that has to be written and maintained.		The feature is checked against the model on every call.
The figure the order statesOnly with care
The maximum pressure stated in the order is a free-entry field; a rule has to look up the right table row and compare.		The stated figure is a field in the request, compared with the datasheet figure for the model on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a Davey HM Series home pressure system (Torrium2 models HM60-06T to HM160-19T, or the pressure-switch models HM270-19P and HM270-25P) for a fictional rural property services contractor: the model, the flow and pressure the job needs, the water, and more. Before the order goes out, the agent sends it to Predictika, which checks it against a declarative model of what the public Davey datasheets say and returns a verdict, every reason and the figures it computed. The customer is fictional.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a Davey HM60-08T pressure system for a job that needs 50 litres a minute at 300 kPa. The water is 20 C with 5 g per cubic metre of sand and an inlet pressure of 50 kPa, and the pump room reaches 30 C. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with one finding, all in one answer. The tank is set to 320 kPa air pre-charge; the datasheet gives 400 kPa for this model.
    6. 
      
  6. The validator returned one blocking finding in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for limits that differ by controller type, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the tank air pre-charge to 400 kPa.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. The earlier finding is cleared, and the validator's figure matches the quote.
    13. 
      
  13. One problem caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
