Dividing and Collecting Breechings

A dividing breeching is used in firefighting to split a single incoming water supply into two separate hose lines.

It allows one hydrant, pump, or riser feed to be distributed to multiple outlets so crews can operate more than one line at the same time. Each outlet can be individually controlled, which helps manage flow, balance pressure, and improve flexibility on the fireground.

It is commonly used in structural and high rise firefighting, as well as general utility water distribution where a single supply needs to support multiple operations efficiently.

A collecting breeching is used in firefighting to combine two or more hose lines into a single outlet.

A dividing breeching splits one incoming water supply into two or more outlet hose lines, allowing multiple attack lines to be fed from a single source.

A collecting breeching does the opposite. It combines two or more incoming hose lines into a single outlet, increasing available flow into one hose, pump, or system.

Yes, breechings can affect both pressure loss and overall flow performance.

Because dividing and collecting breechings introduce internal pathways, valves, and directional changes in the water stream, they naturally create some resistance. This can lead to minor pressure loss, especially if both outlets are in use on a dividing breeching or if multiple inlets are not balanced on a collecting breeching.

Yes, dividing and collecting breechings can be used for foam solution as well as water, provided the equipment is compatible with foam systems.

In foam operations, a dividing breeching can split a single foam or water feed into multiple lines, allowing several branches or nozzles to operate simultaneously. A collecting breeching can combine multiple foam or water lines into one supply where higher flow to a single application point is required.

Delta Fire dividing and collecting breechings are commonly manufactured from light alloy or gunmetal, both chosen for strength, durability, and firefighting performance.

Light alloy breechings are significantly lighter, which improves portability and reduces firefighter fatigue during deployment, especially in mobile or high rise setups.

Gunmetal versions are heavier but offer increased robustness, corrosion resistance, and long term durability, making them well suited to harsher industrial, marine, or high wear environments.

Both materials are designed to withstand high pressure operation, so the choice mainly comes down to balancing weight versus long term durability and environmental exposure.

To maintain breechings and prevent corrosion or sticking, they should be thoroughly cleaned with clean water after each use to remove dirt, foam residue, and contaminants.

All moving parts such as valves, threads, and couplings should be checked for smooth operation and lightly lubricated if required using an appropriate firefighting compatible lubricant. This helps prevent seizing and wear over time.
