A washing machine drain pan can contain a small leak and direct water toward a suitable drain, but it is not a repair for a loose hose, failed valve, overflowing standpipe, or damaged floor. In a manufactured home, the useful question is not simply whether a pan fits under the appliance. You also need access, a safe drain route, adequate floor support, and enough clearance to service the washer.

When a drain pan helps
A pan is most useful for slow drips from the appliance body or supply connections. A pan with a correctly installed outlet can move that water away from finished flooring. It may also make a minor leak easier to notice. It cannot handle every sudden hose failure, and a pan without a drain can overflow.
If you are still locating the source, start with the manufactured-home leak detector placement guide. For moisture that appears without an active leak, compare the pattern with the guide to laundry-room humidity.
Measure the washer and the route
- Measure the appliance width and depth at the feet, not only at the cabinet.
- Record hose, cord, door, and filter-access clearances.
- Check the pan’s inside dimensions; outside dimensions alone can be misleading.
- Plan how the washer will be lifted without bending the pan or damaging flooring.
- Identify where the pan outlet would discharge and whether local rules allow that route.
Leave enough room to close closet doors and remove service panels. For a front-load washer, confirm that the pan lip will not block the lower access door. A shallow lip is easier to cross but holds less water; a taller lip can interfere with servicing.
Drain connection versus catch-only pan
A catch-only pan buys time but requires regular inspection. A drained pan needs a compatible fitting, a continuous route with appropriate fall, and a safe termination. Do not connect it casually to the washer standpipe, cut the floor, or alter plumbing without checking the appliance instructions and local requirements. Manufactured-home plumbing can differ in routing and access from site-built construction.
This Old House’s drain-pan overview covers common plastic and metal pans, outlets, installation, and maintenance. Treat it as general information; the manufacturer, local code authority, and a qualified plumber should decide the actual connection.
One pan to compare against your measurements

Confirm the current inside dimensions, outlet size, material limits, and installation instructions on the live listing before purchase. This is not a field-tested recommendation.
Installation and safety checklist
- Shut off water and disconnect power according to the washer manual before moving it.
- Use enough people or proper lifting equipment; washers are heavy and awkward.
- Do not crush the drain hose, supply hoses, wiring, or under-floor services.
- Keep the washer level and verify that every foot rests securely.
- Run a supervised fill, drain, and spin cycle, then inspect every connection.
- Recheck after 24 hours and after the first week.
Water and electricity are a hazardous combination. Stop if you find damaged wiring, a warm outlet, a soft floor, corrosion, or an active leak near electrical equipment. Do not rely on a pan while delaying repair.
Maintenance that keeps the pan useful
Keep the pan visible and free of storage. Dust and lint can hide a slow leak or block an outlet. Inspect supply hoses, clamps, valves, the standpipe, and the pan perimeter on a schedule. A leak detector placed where water reaches it early adds warning; it does not replace inspection or automatic shutoff equipment.
Frequently asked questions
Does every manufactured home require a washer pan?
Requirements vary by location, installation, and whether the washer is above occupied space. Check the home documentation and local authority instead of assuming a universal rule.
Can I put a pan under a stacked washer and dryer?
Only if the pan, floor, appliance, and lifting method can safely support the complete stack and service access remains available. Follow both appliance manuals.
Will a pan stop mold?
No. It can contain some liquid water, but trapped moisture, condensation, and hidden leaks still need diagnosis, drying, and repair.
Bottom line
Choose a drain pan by inside dimensions, outlet plan, service access, and the washer manual. Install it as part of a leak-management system—not as permission to ignore hoses, drains, wiring, or floor damage.
