Summary
What this review covers
This review focuses on the tubing size, 100 foot roll length, blank mainline role, and fit for faucet-fed backyard drip irrigation planning.
Pros
The upside
- The 100 foot roll supports a continuous mainline path through beds, borders, and container groups.
- The 0.700 inch outside diameter gives gardeners a clear fitting size to plan around.
- Blank tubing keeps emitter placement and branch routing open during layout work.
Cons
The tradeoffs
- The 0.700 inch tubing size needs matching fittings before installation begins.
- The roll still needs stakes and end closures to keep the final route tidy.
Who it is for
Fit and feel
Good match:
Choose this roll when the layout is being planned around 0.700 inch outside-diameter tubing and compatible fittings are ready for the installation.
What to know:
Leave a little working length at the faucet side and at the end of each route. A small amount of slack makes flushing, staking, and seasonal adjustment easier.

Breakdown
Full review
A clear size for a mainline route
The Rain Bird T70-100S Drip Irrigation 1/2 Inch Blank Distribution Tubing is a 100 foot roll of black 0.700 inch outside-diameter tubing. It serves as the mainline in a drip setup where the fittings, faucet connection, and route plan are chosen around that diameter.
Blank tubing gives the gardener control over the layout. The line can run along a bed edge, around shrubs, beside patio containers, or through a greenhouse bench before branch points are added.
The diameter is the key detail
This roll lists a 0.700 inch outside diameter and a 0.600 inch inside diameter. That sizing should be checked against the planned fittings, tees, elbows, couplings, and closures before the tubing is cut.
The route itself benefits from soft curves and visible stake points. Marking corners and water points before cutting helps the line feel organized once mulch and foliage fill in.
Useful for a planned drip shelf
This tubing belongs with a faucet-side pressure regulator, backflow protection, filter, timer, branch fittings, and small refill parts. Keeping those pieces together helps the system stay understandable during watering checks.
The 100 foot length gives a home gardener room to route around several nearby planting zones while keeping the line easy to find and service.
