Upwardly mobile: A pool cart, stocked with essential tools, can be towed behind a tech’s truck and then wheeled directly to the job site.

Pool service technicians rely on a variety of tools made especially for their job, including nets, vac hoses and lid wrenches. But it’s the range of tools not made specifically for the pool industry that form the backbone of their fix-it arsenals.

Here’s a look at what service experts say should be found in your toolbox — and how these tools come in handy on the job.


Allen wrenches A set of Allen wrenches can be purchased in a plastic case or in the “jackknife” style, where each wrench is folded out of a case one at a time.

Veteran tech Bob Blade carries both kinds. “The jackknife style is great because it keeps them all together. But sometimes you just need the single wrench, and the jackknife style can be cumbersome,” says Blade, owner of Aloha Pool & Spa Service in Pacific Grove, Calif.

Allen wrenches are important because they’re often needed for brand-name-specific jobs. “I use a 1/16-inch for the Laars heater thermostat knob, and the 1/8 -inch for the old Sta-Rite motor,” Blade says.

Chisels Experts recommend that techs keep on hand an array of chisels: metal, stone, wood and even a putty knife.

“Wood chisels are for scraping old gaskets off pumps, or calcium off tiles,” Blade says. “A cold steel chisel is for cutting bolts and other metal cutting.”

Blade also keeps a carbide tile and masonry chisel on hand for chipping work and cutting out tile.

Files Although most of today’s equipment is plastic, techs still suggest having a 10-inch, half-round mill file for metal work. It can come in handy when dealing with bronze pump bodies, to clean off burrs, or to fix bent or corroded lids.

Goggles and gloves For goggles, purchase the splash-proof kind for chemical handling, and the vented ones to prevent fogging. Experts recommend goatskin or deerskin gloves.

Grooved-joint pliers These pliers often are referred to as “Channel Locks,” a common brand name.

They’re good for grabbing onto pipes and twisting, as well as loosening filter nuts. Don’t use them to tighten PVC unions and filter unions, or you’ll crack the nut, says Blade.

David Hawes, owner of H&H Pool Services in Dublin, Calif., says his pair of grooved-joint pliers is essential. “If I have to grab only a couple tools off the truck to go do some troubleshooting, it’s my screwdrivers and Channel Locks,” he says. “They get me through a lot of things.”

Hawes brings several sizes including a small model, and the standard 12-inch size. “I have a huge one to loosen filter bulkhead fittings. You can use them instead of pipe wrenches. It is a very universal tool,” he explains.

Hammers Most techs have a collection of hammers. Blade uses a hammer and a long block of wood to remove old-style steel filter band clamps, or to loosen fitted pump lids.

Rubber mallets also come in handy. “I use a rubber mallet to put filter-lid clamps in place and to hit anything that might otherwise be damaged by using a conventional hammer,” says Steve Jones, owner of Anglo-American Pool Service & Repair in Torrance, Calif.

Avoid wood-handled hammers because most of the work takes place around water, and the wood can decay over time when constantly exposed to moisture. Steel, graphite and fiberglass handles are good alternatives.

Leatherman Wave When it comes to all-purpose tools, look for something called the Leatherman. “By far, the best tool for every pool and spa service [tech] would have to be the inimitable Leatherman Wave,” Blade says.

The device includes two switchlike blades, four screwdrivers (including a Phillips), a sharp saw that can cut up to 2-inch PVC, a hacksaw with an industrial diamond-fused file, scissors, a can opener, wire strippers and needle-nose pliers.

“It’s what most paramedics, firefighters, military and other service trade workers have on their belts as the compact multi-tool of choice,” Blade says.

Needle-nose pliers “Every toolbox needs a pair of needle-nose pliers,” Blade says. “But be sure it’s equipped with wire cutters.”

Experts suggest carrying two styles: long and narrow for getting at hard-to-reach places, and short ones that can be used primarily as wire cutters.

“Needle-nose pliers are good for holding wires onto relays, so you can tighten them down,” Hawes says. “Mine probably gets used more than any other tool in my box, other than the screwdriver.”

Blade says the longer pliers are good for removing leaves, hair and other debris from pump impellers.

Pipe wrenches Commonly known as monkey wrenches, they’re good to have around even with the advent of plastic pumps and PVC plumbing. “I think Rigid makes the best, no substitutes,” Blade says. “I have a 24-inch lightweight aluminum type with offset ‘bulldog jaws.’ I don’t used it much anymore except on 1-inch gas lines and big brass pumps.”

PVC pipe cutters This tool is essential for getting clean cuts on PVC piping, whereas a hacksaw won’t give an even cut. PVC pipe cutters come in several sizes.

Screwdrivers Sometimes the most basic tool is also the most essential. “I have three different sizes of the flat blades, and two sizes of Phillips,” Hawes says. “I carry one for lock screws on pumps and for the motor shaft. I use a big one like a chisel or pry bar. I use a very skinny one, about 1/8-inch wide, for electrical work — things like faceplate screws. I also carry very tiny screwdrivers for working on terminals inside controllers.”

Blade says he’s been using a 6-in-1 combination screwdriver set available from hardware stores at a cheap price. “You can leave a set at all your commercial pools,” he says. “They’re cheap, so I buy one just about every time I go into the store.”

It’s important to replace screwdrivers if they get even the slightest bit worn, Hawes says; otherwise, the screws can be easily stripped.

Standard nut drivers Veteran service techs say the 1/16 - and 1/4 -inch tools are crucial sizes to carry for pool work. “The 5/16 is the standard nut size on most terminal connections,” Hawes points out.

The tools are important for removing motor bolts, radiator hose clamps and heater tops.

“I generally use nut drivers to dismantle heaters because the variety of the drivers make the job easier than using an ordinary screwdriver,” Jones says. “Hex nuts and screws can be removed and tightened easier with nut drivers.”

Toolmakers also are making them user-friendly. “They come color-coded nowadays,” Hawes says. “For example, I know that the yellow is 5/16 and the red is 1/4-inch.”

Standard wrenches Although many manufacturers make filters and pumps that techs can take apart without tools, experts say plenty of the old-style equipment is still out there, and that requires wrenches.

Stock wrenches in sizes from 3/8 through 9/16, as that will cover most motor bolts and such, experts say. “I also carry a 1/4 -inch and 5/16, open and box end,” Hawes says. “These are good for getting into places where there is no clearance and you can’t use a nut driver.

“Many techs also carry an adjustable crescent wrench, in case they’re not sure of the size of the nut,” he adds.

Wire brushes Brass or stainless steel brushes won’t rust and are good for cleaning around brass pumps. Brushes designed to work on plastic and PVC are available, so look for those with nylon bristles, or use an actual toothbrush on those kinds of jobs.

Wire strippers These are used for removing the plastic coating on wires and exposing the copper inside. Blade favors the GB or Klein brands. He also likes the new automatic wire strippers — hand-operated, labor-saving devices with springs and levers.


3/8-inch electric drills and bits These drills are perfect for installing flow meters, gauges, feed pump tubing and so forth.

“I have three of them,” Blade says. “Two are battery-operated and one is [A/C] electric. They have variable speeds, are reversible. Everyone has their favorite.”

Jones finds his battery-operated drill very useful. “It’s invaluable if you need to drill and tap a new thread into a brass pump pot lid that has worn out,” he explains. “It’s also good for removing screws and nuts while tearing down old equipment. I use it in place of a power screwdriver.”

Hole saws These saws are good for cutting into control system boxes and electrical time clock boxes to facilitate electrical conduit connections when there are no longer any available knockouts.

Power saws “I use the reciprocating saw for speed and efficiency,” Jones says. “I use it primarily for the removal of pool equipment, and also installations and plumbing repair.”

Blade uses a Sawzall brand power saw. “It’s great for cutting large pipes and comes with a wide variety of blades, including diamond for cutting tile,” he says.

Power screwdrivers Besides using them on screws, power screwdrivers can be used to drill. They are particularly helpful for drilling holes for temperature sensors.


25-foot steel tape measures Jones calls his tape measure “one of the most essential tools in my kit.” Blade keeps a 100-foot, fiberglass measuring tape on hand to determine pool length when he needs to calculate volume or size a new pool cover.

Marking pens Indelible marking pens, such as Sharpies, have a variety of uses. “I use a Sharpie for labeling [equipment, valves and meters] in the pump house,” Blade says. “It will tell what the multiport valves are for, where the automatic cleaner is, etc.”

Hawes uses them to benchmark filter gauges when cleaning filters. “It’s good for troubleshooting,” he explains. “We note where the clean mark is on the pressure gauge and if there is a problem in the future, we know where that point is.”
