Location and Shut-Off Notes: Finding the Water Heater and the Main Before the Plumber Walks In

Every plumber has spent ten minutes looking for a main shut-off. Behind the washer. Under a pile of boxes in the basement. In a meter box at the curb covered by a foot of mulch. In a crawlspace hatch inside a closet nobody mentioned. Ten minutes is annoying on a routine call. On a leak with water running across the floor, it is the whole job. Location and shut-off notes in the PlumbingBossPro tech app put that answer on the card.

Notes That Belong to the Equipment

The equipment list itself is covered in The Equipment Card: Water Heater Type, Brand, Model, Serial and Size on Every Plumbing Job. Every item on that list can carry a location and access notes, and those notes show on the plumber's phone under the equipment details.

Because the notes belong to the equipment on the house, not to a single job, they are there every time the address comes up. The plumber who found the shut-off behind the furnace in March writes it down once, and the plumber who gets the emergency call in November reads it before opening the van door.

The Main Water Shut-Off

The main shut-off is the most valuable note a plumbing company can keep. A good one says where it is and how to work it:

• “Shut-off is in the meter box at the curb. Needs a meter key.”
• “Basement, front wall, behind the water softener. Gate valve, stiff.”
• “Inside the garage on the left wall, ball valve above the hose bib.”
• “Crawlspace, access hatch in the hall closet floor. Valve is near the hatch.”

Notes about condition are just as useful. “Old gate valve, does not fully close” tells the next plumber to plan on the curb stop instead, and it gives the office something to quote.

The Water Heater's Location

Water heaters hide in more places than people expect. The location note tells the plumber where to go and what they will be working around:

• “Garage, left of the door to the house.”
• “Attic, pull-down stairs in the upstairs hallway. Tight clearance.”
• “Utility closet off the kitchen. Must move the shelving to reach the drain valve.”
• “Basement, next to the furnace. Drain valve faces the wall.”

For a flush visit, knowing the drain valve faces the wall or that the hose will need to run through the garage saves real time. For a replacement, knowing the tank is in the attic changes how many people need to be on the job.

The Cleanout and Everything Else

Drain calls need the sewer cleanout, and cleanouts are famous for disappearing under landscaping. “Cleanout is in the side yard by the AC unit, under the river rock” is a note that pays for itself the first time a drain tech is dispatched to that house. The same goes for the sump pump pit, the sewage ejector, the softener's bypass valve and the backflow preventer outside a restaurant.

Access notes for getting in the door belong here too: lockbox codes for rentals, “tenant works nights, call before 11,” “use the side door, dog in the front room.”

Who Writes the Notes

Notes get written in two places. The office adds what the customer says on the phone, such as “the tank is in the garage.” The plumber adds what they actually find on site, which is usually more precise. When a plumber learns something new, they put it in the job notes, and changes made on a job flow back to the house, so the next visit shows the corrected location.

The habit to build is simple: if you had to look for it, write down where you found it. That rule alone fills in the shut-off and cleanout locations for most of your customer list within a season.

Why It Matters on Emergency Calls

On a planned flush, a missing location note costs a few minutes. On an emergency, it costs water damage. When a customer calls with a burst line, the office can read the shut-off note to them over the phone so they can stop the water before the plumber arrives. The plumber then walks in already knowing where to go.

It works the same for property managers. A tenant calling about water spreading across the laundry room floor rarely knows where the main is. The manager, or your office, can open the address and tell them within seconds. That kind of help in a stressful moment is what customers remember when they choose who to call next time.

Past notes from earlier visits sit right alongside the equipment and locations, and they are the subject of Reading Past Notes in the Plumber App Before Knocking on the Door. For the whole job card and the rest of the tech app, see the PlumbingBossPro plumber app page.
