- Job complexity: Longer drain lines or multiple modifications increase labor fees.
Most buyers miss this: Always inspect your existing setup before purchasing a new dishwasher.
Does Professional Installation Include Appliance Removal?
Professional installation typically includes appliance removal for an additional $30-$100, depending on local recycling fees. Some services bundle removal with installation for convenience.
For example, Sammy's Appliances offers removal as part of their standard installation package. However, always confirm this with your installer beforehand, as policies vary.
When Does Dishwasher Installation Require Plumbing Work?
Dishwasher installation requires plumbing work when drain lines exceed 12 inches from the disposal (IPC standards) or when shutoff valves are missing or faulty.
Here’s a checklist:
- Drain line distance: Max 12 inches from disposal
- Shutoff valve: Must be functional and accessible
- Drain hose height: Must loop above the dishwasher to prevent backflow
If any of these conditions aren’t met, expect additional plumbing costs.
