Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the liquid expands, it shatters its glass confines and the sprinkler head activates.

Are all sprinkler valves the same?

There are many different kinds of irrigation valves available. You will need at least two different types for your irrigation system.

How do I identify sprinkler heads?

Let’s get to it: a sprinkler identification number consists of one or two letters followed by three or four numbers. That code is imprinted on each sprinkler’s deflector—the thin metallic part furthest away from a sprinkler’s threaded inlet.

Are all sprinkler heads the same?

A replacement sprinkler head doesn’t have to be the same brand as the broken head. But it does have to be the same type: pop-up (stationary, rotor- or gear-driven rotor) or impact. And the new head must also match the inches-per-hour (iph) or gallons-per-minute (gpm) delivery rate of the old head.

How many types of sprinkler heads are there?

There are three basic sprinkler head types– Spray Irrigation Heads and Spray Rotary Sprinkler Heads, Bubbler Irrigation Heads, and Drip or Soaker Systems. Each different sprinkler head will water your plants in the particular way they like.

Can I mix and match sprinkler heads?

While you can mix different brands in the same zone, don’t mix the type of head because they have different flow rates. Rotor heads, spray heads, matched precipitation etc all throw water at a different rate.

How do I identify my sprinkler valve?

Start at that sprinkler and try to find the valve nearby. The cheapest and easiest way to find buried irrigation valves is often to probe the soil with a thin rod, such as a long screwdriver. Often you can estimate the rough location of the irrigation valve, then find a buried valve box by probing the ground.

How do I find sprinkler heads?

Measure the distance between visible sprinkler heads with a measuring tape. Sprinkler heads will likely be spaced evenly in a set pattern across your landscape. Look for an unusually wide gap between otherwise evenly spaced heads; a buried sprinkler head may sit midway between them.

Do all sprinkler systems have a master valve?

The irrigation controller turns the master valve on and off. Most, but not all, irrigation controllers have a master valve circuit built in to them.

Why is sprinkler water black?

Iron-related bacteria (which either metabolize or create deposits of iron) Slime-forming bacteria (iron-related bacteria that generate white, beige, grey, or black slime) Sulfate-reducing bacteria (which may turn water black and are responsible for much of discolored water’s smell in fire protection systems)
