Refill speed matters more than range
Every water fight ends the same way — at the tap. A blaster that refills from the pool in one second changes the game more than an extra ten feet of range ever will.

The blaster
Large reservoir, pump action, and a wide dunk-fill opening. That last one is what keeps the game going.

The short version
- Dunk-fill is the feature to buy on. A wide opening that refills from the pool in a second is what keeps a game going.
- Pump action beats pressurized tanks for reliability — there is no pressure vessel to fail.
- Big reservoirs are heavy when full, which quietly rules out the smallest children.
- One rule, stated before they are handed out: not at faces. Range and pressure are the selling points and the reason for the rule.
The spec that decides everything
Refilling. Every water fight has the same failure mode: someone runs out, walks to the tap, spends a minute filling through a narrow cap, and by the time they are back the game has moved on. Do that twice and the toys go in the shed.
Dunk-fill designs — a wide, unscrewing opening you push straight into the water — solve it completely. Current blasters advertise a one-second refill from a rotating screw opening, and at a pool you are standing in the reservoir. That is the whole reason water guns belong on a pool site rather than a toy site: the refill problem does not exist here.
| Spec | Typical | What it means |
|---|---|---|
| Reservoir | Around 1,200 cc on large blasters | More shots per fill, more weight to carry |
| Range | Up to about 34 ft, pump action | Beyond about 20 ft, accuracy collapses anyway |
| Refill | Dunk-fill wide opening | The single most important feature |
| Action | Pump rather than trigger | Needs two hands; nothing pressurized to fail |
| Material | ABS, non-toxic, toy standard | Cheap plastic cracks at the pump seal |
| Sealing | Rapid-seal or equivalent | Leaks are the standard failure mode |
Range is the number on the box and the least useful one. Thirty-four feet is further than any backyard pool is wide, and past about twenty feet a stream breaks up and stops being aimed at anything. Buy for capacity and refill; take the range figure as a proxy for how well the pump is built.
Two-handed, and what that rules out
Pump action means one hand holds and one hand pumps. For an eight-year-old that is fine. For a four-year-old holding a full 1,200 cc reservoir, it is not — the toy is too heavy to aim and too awkward to pump, and it gets abandoned in the first five minutes.
For that age group, a smaller trigger pistol works far better, and a splash pad works better still — it requires nothing at all from the child and runs in a few inches of water. Our pools for kids guide covers the wider age-matching question.
Looking after them, which takes thirty seconds
Empty them. Water left in a reservoir all week goes stagnant and smells, and on a hot deck it grows things. Tip them out at the end of a session.
Dry the pump. The seal at the pump shaft is where leaks start, and it lasts longer dry than wet.
Store them out of the sun. Same rule as every other plastic item at a pool — UV is what makes cheap ABS brittle, and a brittle pump housing cracks on the first hard pull.
What we are scoring
We have not tested these and do not claim to. The scores reflect published specifications — reservoir capacity, stated range, refill mechanism and material — against use in and around a backyard pool. Our methodology page explains how our scoring works.

Pick #1 · The cheapest hour of entertainment in the yard
Pump-Action Water Blaster
Various
A large-reservoir pump blaster with a dunk-fill opening. Range and refill speed are the two specs that decide whether it gets used twice or all summer.
Key specs
- Reservoir
- Around 1,200 cc on the larger blasters
- Range
- Up to about 34 ft on pump-action models
- Refill
- Dunk-fill wide opening — seconds, not minutes
- Material
- ABS, non-toxic, US toy quality standard
- Action
- Pump-action rather than trigger-pressurized
- Sealing
- Look for rapid-seal or equivalent anti-leak
How it scoresour reading of published specs, not a test result
- Range
- 8.0
- Capacity
- 8.5
- Refill
- 9.0
- Build
- 6.5
- Value
- 9.0
Overall 8.2 / 10
What works
- Dunk-fill is the feature that matters — refilling at a tap is what ends water fights
- Pump action gives real range without a pressurized tank to fail
- Large reservoirs mean fewer refills and longer games
- Works from the pool, which is the whole point of buying one for a pool
What doesn't
- Leaks are the standard failure and they start at the seals within a season
- Bigger reservoirs are heavy when full, which rules out the smallest children
- Pump action needs two hands, unlike a trigger pistol
- Left full in the sun, the water inside goes stagnant fast
Skip it if: Being aimed at faces, which is the one rule worth stating before handing them out. Range and pressure are the selling points and the reason for the rule.
What it costs to run: No running cost at all beyond the water, which comes from the pool you already filled. Empty and dry them at the end of a session and they last more than one summer.
One honest season: The cheapest setup that genuinely works for a season of real swimming. Nothing spare, nothing missing.

Pick #2 · The age group too small for the pool
Inflatable Splash Pad Sprinkler
Various
A hose-fed inflatable mat that sprays upward. It solves the problem of a toddler who wants to be in the water while the pool is genuinely too deep for them.
Key specs
- Size
- Commonly 60 to 68 in across
- Water
- Standard garden hose connection
- Material
- Thick PVC, non-toxic, no sharp edges
- Surface
- Non-slip texture on the better mats
- Depth
- A few inches — that is the whole safety argument
- Setup
- Inflates from the water supply itself on most
How it scoresour reading of published specs, not a test result
- Material
- 6.5
- Valve
- 8.0
- Capacity
- 7.0
- Storage
- 9.0
- Value
- 8.5
Overall 7.8 / 10
What works
- A few inches of water instead of four feet, which changes the supervision picture entirely
- Inflates and drains in minutes, so it does not live in the yard all summer
- Non-slip surface texture is standard on current models
- Cheap enough to treat as a one- or two-season item
What doesn't
- Runs continuously off the hose, so it is using mains water the whole time it is on
- Thin PVC punctures on anything sharp in the lawn underneath
- Only works while the hose is running — no water, no toy
- Kills the grass underneath it if left in one place
Skip it if: Replacing supervision. A few inches of water is still water, and CPSC guidance on young children applies to a splash pad as much as to a pool.
What it costs to run: The running cost is the hose. Unlike a pool, the water is not recirculated — it soaks away, so this is genuinely metered water for as long as it is on.
One honest season: The cheapest setup that genuinely works for a season of real swimming. Nothing spare, nothing missing.

Pick #3 · Keeping kids in the pool for an extra hour
Weighted Dive Toy Set
Various
Negatively buoyant rings and sticks that sink and stay put. Cheap, indestructible, and the single best return on money in a pool with children in it.
Key specs
- Type
- Weighted rings, sticks or discs
- Buoyancy
- Sinks and stays upright on the floor
- Material
- Rubber or weighted plastic
How it scoresour reading of published specs, not a test result
- Material
- 9.0
- Valve
- 10.0
- Capacity
- 6.0
- Storage
- 9.0
- Value
- 9.5
Overall 8.5 / 10
What works
- Nothing to inflate, nothing to puncture, nothing to store carefully
- Works in a 30-inch pool where most float toys do not
- Genuinely encourages swimming rather than sitting
What doesn't
- Bright colors fade and then they are harder to find on a blue liner
- Hard edges on cheap sets can mark a vinyl liner
- Small parts, so check the age rating for younger children
Skip it if: Very shallow water, where there is not enough depth to make retrieving them interesting.
Several seasons: Buy-once. Built and warranted to come back out of the box for a few years, if you store it properly.
