Watering & Irrigation

Hose Diameter, Length and Pressure

Diameter is the specification that decides flow, and 5/8 inch is the default that fittings, reels and nozzles are designed around. Half-inch hose is lighter and flows less. Three-quarter-inch hose flows more and is heavy enough that most households regret it.

Length costs pressure.

A 100-foot run at the same diameter delivers noticeably less at the nozzle than a 50-foot run, which matters for sprinklers rated by coverage. Buy the shortest hose that reaches, and add a second length only when it is genuinely needed.

Hose at 214 of 475 listings is the largest block in the collection.

Expert Gardener at 48 and Gilmour at 26 carry most of the household range, with Teknor Apex covering the commercial grades.

Hose Thread and Fittings

US garden hose thread is a single standard, which is why almost anything screws onto anything here. The exception is quick-connect systems, which are brand-specific and will not mate across manufacturers even though both ends are threaded underneath.

Brass fittings outlast plastic ones by years and cost a few dollars more.

A crushed plastic coupling is the most common reason a working hose gets thrown away.

Nozzles, Wands and Sprinklers

64 listings are nozzles and 47 are sprinklers, and the two solve different problems. A nozzle waters what you point it at. A sprinkler waters an area while you do something else.

Sprinkler coverage here is stated from 64 to 5,600 square feet, with 3,850 the median. Oscillating sprinklers throw a rectangle and suit lawns with straight edges, while impact sprinklers throw a circle and overshoot corners.

Measure the area before buying on coverage.

A sprinkler rated at 3,850 square feet is rated at full pressure on a short hose, and neither of those usually applies.

Drip Line and Timers

22 listings are drip and 23 are timers, and the two belong together. Drip line delivers water at the root rather than over the leaves, and it only works reliably on a timer because the flow rate is too slow to stand and watch.

Emitter spacing is the specification to check, since it has to match plant spacing rather than bed length.

A 12-inch emitter line in a bed planted at 18 inches wastes a third of its output.

Storage and Barrels

Hoses kink where they were last coiled, and storage is what determines how long one lasts. The reels in hose reels and storage are sized by hose capacity in feet rather than by their own dimensions.

A rain barrel spigot is a hose thread, so a soaker or drip line connects directly, though barrel pressure is gravity only and will not drive a sprinkler.

Watering Questions

What hose diameter should I buy?

5/8 inch. It is the standard that fittings, reels and nozzles are built around. Half-inch flows less and three-quarter-inch is heavy enough that most households regret it.

Does hose length affect pressure?

Yes. A 100-foot run delivers noticeably less at the nozzle than a 50-foot run at the same diameter, which matters for sprinklers rated by coverage.

Do quick-connect fittings work across brands?

No. The underlying hose thread is a single US standard, but quick-connect systems are brand-specific and will not mate.

What sprinkler coverage do I need?

Measure the area first. Ratings here run 64 to 5,600 square feet, and they assume full pressure on a short hose, which rarely describes a real garden.

Can a rain barrel run a sprinkler?

No. Barrel pressure is gravity only. A soaker or drip line connects directly to the spigot thread and works; a sprinkler needs mains pressure.
