Gilmour 315MTL Bubbler Sprinkler

Gilmour 315MTL Bubbler Sprinkler – Specifications

What is a bubbler sprinkler and how is it different from a regular sprinkler?
A bubbler sprinkler delivers water at ground level in a gentle, low-pressure flow — more like a steady seep than a spray. Unlike conventional sprinklers that project water through the air (which leads to wind drift, evaporation, and potential leaf disease), a bubbler applies water directly to the soil surface so it soaks straight down to the roots. This makes it ideal for delicate plants, newly transplanted seedlings, and container gardens where soil disturbance or overwatering is a concern.

What does the Gilmour 315MTL connect to?
The 315MTL connects directly to a standard garden hose. It uses a standard hose-end fitting, so no adapters, tools, or special fittings are needed. Just thread it onto the end of your hose and place it where you need to water.

What is the maximum water pressure for the 315MTL?
The Gilmour 315MTL is rated for a maximum of 60 PSI. For the best results and the gentlest possible flow, use it at lower pressure. If your home's water supply pressure is high, consider attaching a pressure regulator to your hose bib before the bubbler to dial in a softer, more controlled output.

Why is the aluminum construction important?
Aluminum resists rust and corrosion better than plastic alternatives, making it suitable for year-round outdoor use and extended storage. It also provides a heavier, more stable base so the bubbler stays put while in use rather than being pushed around by the hose or water pressure. The durability of the aluminum body is why Gilmour backs this product with a Lifetime Warranty.

What plants and garden areas is this best for?
The 315MTL excels anywhere you need targeted, low-disturbance watering: fragile annuals and perennials, vegetable garden beds, newly seeded areas, flower borders, potted container gardens, raised beds, shrubs at ground level, and any area where heavy spray would erode soil or compact a mulch layer. It is particularly useful for watering into tight spots that larger sprinklers can't reach.

Can I use this with a timer to automate watering?
Yes. Because the 315MTL connects to a standard garden hose, it is fully compatible with any hose-end irrigation timer from DripWorks. Simply attach the timer to your hose bib, connect your hose, and run the bubbler on a set schedule — perfect for consistent, hands-free garden care.

How does a bubbler prevent soil erosion?
High-pressure sprays create impact energy when water hits the soil, which physically dislodges soil particles and washes them away — especially in bare or loosely amended beds. A bubbler dissipates the water's energy before it reaches the soil, so water pools gently and percolates down rather than bouncing off and running over the surface. This keeps your mulch layer intact and your amendments in place.

Is there a drip-system bubbler option if I want to integrate this into my irrigation system?
Yes. If you'd like to incorporate bubbler-style watering into a drip system rather than running a garden hose manually, DripWorks carries the Adjust-A-Bubbler (1/4" barb or 5" spike, adjustable 0–35 GPH) and Jain Octa-Bubblers for multi-outlet container setups — both designed for permanent in-line drip installation.
