Plumber Radios

The main water line just burst in the basement. The lead plumber is ankle-deep in water and needs a part from the truck—now.

The apprentice is upstairs finishing a sink install and has no idea what's happening below.

Meanwhile, the customer is on the phone with building management, asking when the leak will be stopped.

These are all common issues in plumbing - and they can easily be solved with clear, quality two-way radios.

Let's walk through some important components when comparing radios.

Coverage Considerations

When choosing two-way radios for your team, it is important to match radio power and coverage of your building size and layout.

Selecting a radio that is too powerful for your needs can lead to overpaying, while choosing one with insufficient coverage may result in poor quality and dead zones.

For small sites, 1 to 2 watts of power will do the trick - you can get from 100k - 200k sqft of coverage.

Larger sites (or multiple buildings), covering up to 350,000 square feet, require more powerful radios in the 3-4 watt range on analog (or 1 watt on digital) that can transmit clearly through walls and across larger distances.

You also need to take obstructions and building materials into account. If you have thick concrete walls, it may be necessary to go 1-watt stronger.

For unlimited coverage, across multiple locations, consider radios that use LTE and Wi-Fi, like the Motorola WAVE PTX series.

Number of Channels Needed

Channels help segment team conversations, to simplify radio chatter.

Channels can also be used to set up private conversations: “Sarah, call Tom on channel two.”

Sarah and Tom can then have an in-depth conversation over the radio without bothering the rest of the staff.

Quality Brands Make a Difference

You need a radio that is not going to fall apart within a year. You need one that will last so you’re not throwing away money.

Motorola and Kenwood two-way Radios are the most quality brands on the market because they are purpose-built for reliable communication with a durable build.

Designed to be easy to use and intuitive their radio series are affordable, cost-effective and eliminate monthly cell phone plans.

Tested for 5 years of field use, Motorola and Kenwood make sure you see a return on your investment. 

Not to mention the included manufacturer warranty (1-3 years depending on model).
