Why Water Filter Vacation Preparation Matters

Summer is peak travel season, and while your bags might be packed for paradise, your home’s water filtration system still needs a bit of attention. Proper water filter vacation preparation not only helps protect your system while you're away, but also prevents costly water damage and ensures clean, safe water upon your return.

Neglecting this simple step can result in stagnant water, bacterial growth, pressure issues, or even damaging leaks. In this guide, we’ll walk you through how to safeguard your home water filtration system before vacation and recommend key accessories and maintenance tips to protect your investment.

Step 1: Turn Off the Water Supply or Filtration System

If your home will be unoccupied for several days or more, turning off your water supply, or at the very least, shutting down your water filtration system, is a smart move.

Why It Matters:

  • Prevents pressure buildup in filters and housings

  • Reduces the risk of leaks, drips, or burst tubing

  • Avoids unnecessary wear on RO membranes and carbon filters

Tip: If you're using a reverse osmosis system with an auto shut-off valve (ASO), you can isolate the system at the inlet valve. For whole-house filters or systems with large tanks, shutting off the main water supply may be ideal.

Step 2: Install a Leak Detector or Automatic Shut-Off Valve

You can’t predict every issue, but you can plan for them. Installing a leak detection alarm or an auto shut-off valve adds a layer of protection that gives you peace of mind while you’re away.

Recommended Accessories:

  • Leak Detection Alarms: These battery-powered devices emit a loud alert when they sense water. Perfect for RO systems under the sink.

  • Automatic Shut-Off Kits: Triggered by leaks, these systems close the water supply to the filtration system instantly, helping prevent costly damage.

Step 3: Sanitize or Flush the System Before & After Vacation

Water sitting idle in filters or RO storage tanks for extended periods can become a breeding ground for bacteria and other unwanted contaminants.

Before You Leave:

  • Flush the system to remove stagnant water and clear any remaining sediment.

  • Sanitize if your last cleaning was more than six months ago.

When You Return:

  • Flush the system for at least 3–5 minutes before drinking or using the water.

  • Consider replacing your post-carbon filter if your trip lasted 2+ weeks.

Bonus Tip: RO storage tanks like the PAE RO-132 Tank can be depressurized and drained prior to extended absences to avoid stagnation and pressure buildup.

Step 4: Replace Filters That May Have Expired

If your filters are nearing the end of their service life, consider replacing them before you leave. Filters left in a damp, inactive system degrade faster, especially sediment and carbon filters.

Products to Consider:

  • RO Replacement Filter Kits (Includes sediment, carbon block, and membranes)

  • In-line GAC Post Filters for taste and odor control after vacation

Step 5: Check System Pressure and Tubing on Return

Once home, inspect your water filtration system before full operation. Look for:

  • Cracked tubing

  • Leaks around fittings or housings

  • Unusual system pressure or tank performance

If needed, flush the system again and run water through all taps connected to your RO system or filtration units.

Vacation Water Filter Checklist

Before you lock up the house, go through this quick checklist:

  • Turn off the water supply or RO feed valve
  • Drain or depressurize storage tanks if applicable
  • Flush the system pre-departure
  • Sanitize system if overdue
  • Install a leak alarm or shut-off valve
  • Replace any old filters
  • On return, flush system and inspect for leaks
