The problem
A pool’s history should not disappear.
01
A faded invoice in a drawer.
02
A test result in an old phone.
03
A repair only one technician remembers.
04
A warranty nobody can find.
When ownership or service changes, the pool should not have to start over. The record belongs with the pool.
How it works
One pool. One record. Three simple steps.
02
Log what happens
Keep tests, service, repairs, equipment, and inspections together.
03
Keep the history moving
The record stays with the pool through service and ownership changes.
More than a record
A calmer way to own a pool.
Know Thy Pool helps with today’s care, tomorrow’s repairs, and the day the home changes hands.
See trouble earlier
A health score, range alerts, and 30-day trends turn scattered readings into a clearer picture.
Know every piece of equipment
Install dates, models, and warranties stay with the pool instead of a folder.
Share care without sharing passwords
Family members and caretakers use their own access and leave a clear record of what they did.
Give professionals a faster start
A scan puts pool specifications and equipment context at the technician’s fingertips.
Keep useful proof
Dated tests, service, repairs, and inspections show how the pool has been cared for.
Hand over the whole story
When ownership changes, the pool’s history can move with it while old access ends.
