Which equipment specification sheets belong in a commercial plumbing plan review?

Updated October 4, 2026
Quick Answer

Include the exact model specifications for equipment that affects water supply, drainage, hot water, backflow protection or related building systems. Tie each sheet to the equipment schedule and proposed connections. Ask the reviewing authorities which documents they require; a sales brochure does not establish that an installation fits the approved design.

Which information should the equipment schedule collect?

Use a working schedule with one row per installed model:

EquipmentDocuments and details to identify
Water-connected equipmentInlet location, connection size, required pressure and water-quality limits
Drain-connected equipmentDischarge connection, waste characteristics and manufacturer's drain instructions
Water heating or warewashingCapacity and recovery data, temperature requirements and electrical or fuel supply
Food preparation or beverage equipmentListing or sanitation information and the operation it supports
Replacement for an approved modelDifferences in footprint, connections, supply, drainage and installation clearances

This is a coordination checklist. It does not assign a code requirement to every appliance. Have the designer identify the requirements relevant to each unit and the reviewing authority confirm its requested documents.

A bar adding a countertop spray accessory can use the glass-rinser connection review to separate its model instructions from the site’s waste route and approved glasswashing arrangement. For a dental compressor, the moisture-drain planning guide distinguishes dryer, installed intake and receiver drainage before an oil-free label is treated as permission to remove connections.

For a dental equipment schedule, tabletop sterilizer connection planning separates filling water from coolant and discharge connections. For restaurant warewashing, the heat-recovery glasswasher review separates the required inlet from the sanitizing temperature.

For the dish station, compare pre-rinse spray-valve selection using the actual model and task. For ice-cream utensils, the dipper-well review addresses the separate food-contact storage and water-use decision.

How should sheets connect to the drawing?

Label the sheet with the equipment number used on the plan. Mark the selected model and options. Record the document revision, especially if the maker changes connections between models. A unit with an optional drain pump is not the same installation as its gravity-drain version.

Two equipment changes illustrate why the configuration belongs on that drawing: a wet-to-dry dental vacuum replacement can change operating-water connections while retaining wastewater drainage, and a pedicure chair’s gravity or factory-pump option changes the outlet and routing comparison.

For an undercounter ice maker, the gravity-versus-pump drain checklist shows why the exact option and available drain route belong in that comparison.

Two cold-equipment decisions need their own documents: walk-in cooler condensate connections and air-cooled versus water-cooled ice-machine plumbing.

Equipment-specific checklists cover shampoo-sink replacement rough-ins and replacement laundromat washer drainage capacity.

Compare the schedule with the county restaurant plumbing checklist. Check the floor-sink requirements and commercial fixture count separately; a manufacturer's sheet does not decide those design questions.

What should happen before ordering?

Resolve missing connection details and approval conditions before committing to the equipment. Include the documents in the request for quote so installers price the same model. Use the substitution review if availability changes it later. If the proposed assembly includes a Y-strainer, retain its actual model and screen specification with those connection documents.

Before ordering a boilerless cooker, use the steamer replacement checklist to identify its connected or manual-fill arrangement and check whether the existing water treatment is compatible with the selected model.

An accepted equipment sheet also belongs in the closeout file. Keep the approved design and the installed model traceable, so maintenance staff do not inherit instructions for a machine that was never fitted.

For a water-treatment component in that file, the commercial filter-service checklist explains the model and appliance information to pass to the later service provider.
