💧 Low Pressure? Here’s Why It’s Happening — And How to Fix It Like a Pro

The #1 Field Issue We Hear From Pros — Solved.

You’ve arrived at the job. You’ve got your water-fed system ready to roll. But something feels off.

The pressure’s weak. Flow is inconsistent. Rinsing takes twice as long, and what should be a routine clean suddenly turns into a battle.

Sound familiar?

Low pressure isn’t just frustrating — it’s a job-killer. But the good news? Most of the time, it’s caused by a short list of easily fixable issues. Whether you’re running a compact skid or a full-scale trailer setup, here’s what’s likely going on — and how to fix it fast.

❌ 1. Clogged / Dirty Filters: The Hidden Choke Point

Let’s start with the most common (and most overlooked) issue: dirty filters.

Your sediment and carbon filters are the first line of defense in any RO/DI system. And like any frontline, they take the brunt of the abuse — especially in areas with hard water or heavy particulates.

When they clog up, everything downstream suffers. The RO membrane can’t perform, flow rate drops, and your brush loses power.

What to Watch For:

❌ Sluggish system startup

❌ Decreased flow at the brush

❌ TDS readings creeping higher than usual

❌ Visible discoloration or buildup inside the filter housings

If your filters look questionable — they are. Replace them.

📌 Pro Tip:
Swap sediment and carbon filters every 1–3 months depending on usage and local water quality. Think of it as cheap insurance — it protects your RO membrane and keeps your system running strong.

🚰 2. Low Source Pressure: It’s Not You — It’s the Tap

Not all job sites are created equal. In fact, one of the most common culprits behind poor system performance isn’t your gear — it’s your water source.

Whether it’s a rural home, a commercial site with old plumbing, or even just a hose stretched too far, low PSI at the source can choke your entire setup before it even gets started.

Here’s What That Looks Like:

❌ Slower RO production

❌ Reduced water flow at the brush

❌ Inconsistent rinsing — especially on large glass or solar arrays

If you’re dealing with sub-60 PSI at the spigot, your system’s running on fumes.

📌 Pro Tip:
A quality system with a booster pump can make all the difference. At Tucker®, we build plug-and-play booster options that deliver consistent pressure across any job — even in remote areas or long hose runs. Contact a Tucker® Expert to learn more about the options that are perfect for your business.

🎯 Final Takeaway: Don’t Fight Your Gear — Tune It

You shouldn’t have to “muscle through” every rinse. If you’re losing time due to low pressure, it’s time to audit your setup:

✅ Check your filters

✅ Test your source PSI

✅ Consider a bigger system if your area consistently has these issues

The right adjustments can shave serious time off every job — and keep your body (and your margins) in better shape.
