Frequently asked

Does DropTubeBuilder need a signal?

No. Every calculation, error code entry and reference table ships inside the app. It is built for tank pads and forecourts with no coverage.

Which equipment do the error codes cover?

Veeder-Root TLS-300, TLS-350, TLS-450, TLS-450 PLUS and TLS4/TLS-4i consoles; Gilbarco Encore 300, 500S and 700S; Wayne Ovation; and Franklin/INCON EVO 550 and 5000. Pump controller references cover the FE Petro MagVFC and the Guardian SPGC-220.

The recommended actions look different than they used to.

Every alarm and error code now carries an ordered list of things to check, most likely cause first, so you can work it rather than just read what the console already told you. Where an alarm has a regulatory consequence, that is stated at the end rather than in place of the repair steps.

An error code or piece of equipment I work on is missing.

The reference grows with app updates, and requests from working technicians set the priority. Email the brand, the model and the codes you want covered and it gets looked at.

Is a suggested action the same as the manufacturer’s procedure?

No. These are curated summaries to help you decide what to investigate. Always verify against the service manual for the equipment in front of you. See the terms of use.

Is my data private?

Everything stays on your device. No account, no server, no analytics. See the privacy policy.

How do I restore a purchase on a new phone?

Open Settings inside DropTubeBuilder and tap Restore purchases while signed into the same Apple account.

A calculated cut length looks wrong.

Drop tube cut lengths and overfill placement are estimates. Verify against the manufacturer calibration chart and the regulation that applies at your site before anything is cut or installed. If you believe the calculation itself is wrong, email the inputs you used and it is treated as the highest priority bug class.
