Poolmaster 54507 Waterfall Fountain
The $26 experiment — dry climates only — A screw-into-your-return waterfall fountain that cools by evaporation using the pump you already run — the honest expectation is a few degrees in dry air and only 1–2°F on a muggy Gulf-coast night
How to read a Showdown Score™
The only score that counts how often a product breaks, not just how owners feel about it.
- Three parts add up to the score: what owners rate it, how often it fails them, and whether a credentialed tester backed it.
- Bands: Exceptional 8.5 and up, Excellent 7.5, Very good 6.5, Good 5.5, Fair 4, Poor below 4. Every score is dated.
- Price, the warranty and what a link pays us stay out of it.
Fair
Fair is 4.0 to 5.4.

Pros
- Costs less than a pool float and uses no extra electricity — the right first experiment before any four-figure hardware
- Fits most 1.5" threaded return fittings with adjustable spray height and direction
- In dry air it genuinely works: Austin/Phoenix owners report ~4–5°F running through daylight hours
Cons
- Physics caps it in humidity: evaporative cooling can't beat the air's wet-bulb temperature, so muggy Gulf-coast nights yield ~1–2°F net — set expectations accordingly
- Extra evaporation means extra water and a slow pH rise (keep muriatic acid on hand)
- A solid-not-stellar 3.8★ across 1,924 owners — a few complain the spray head pops off; treat it as a cheap experiment, not a precision instrument
It will not stay put. Owners report the compression nut bottoming out before it grips, the elbow swivel working loose so the head droops, and the fountain falling out of the return when bumped. Several could not fit it at all — it needs a 1.5-inch threaded return, and it will not seat on a drain or an undersized fitting.
