FAQ – Laundry Room Plumbing
How long does laundry room plumbing take to install?
Most laundry room additions take 1–2 days depending on how far the space is from existing water and drain lines, and whether any rerouting is needed.
Can you install a washer and dryer in a new location?
Yes! We specialize in relocating laundry hookups, and can add the necessary water supply, drain lines, and proper venting for new washer/dryer setups.
Do I need a permit to add a laundry room?
In most cases, yes—especially if plumbing or electrical is being added or moved. Knockout Plumbing handles all necessary permits and ensures everything is code-compliant and inspection-ready.
What kind of drain is needed for a washer?
A standpipe drain connected to your home’s main drainage system is most common. We’ll make sure it’s properly sized and vented to avoid backups.
Can you install a utility sink along with the washer and dryer?
Absolutely. We often install utility sinks as part of laundry room upgrades, which can be handy for rinsing or pre-soaking items.
