Water Filtration System repair
Your water filtration system is doing its job quietly in the background until it isn’t. If your water suddenly tastes off, pressure has dropped, or something just doesn’t seem right, it usually means the system needs attention.
Royalty Plumbing diagnoses and repairs water filtration systems for homeowners throughout Las Vegas, Summerlin, Henderson, and North Las Vegas. We find the problem, explain it clearly, and fix it right the first time.
- Your filtered water suddenly smells or tastes different
- Water pressure at the kitchen sink or throughout the house has dropped
- The system is leaking at the filter housing or connections
- Your RO tank is filling slower than usual or stopped producing water
- The filter indicator light is on but you're not sure what's actually wrong
- Your softener is running constantly or not regenerating correctly
Quick Answer: Does My Water Filtration System Need Repair?
If your water quality has noticeably changed — taste, smell, pressure, or clarity — the system is telling you something. Most issues come down to a few common causes: a clogged or expired filter, a failing membrane (on RO systems), a pressure or valve problem, or a softener that’s lost its programming or salt bridge.
Some of these are simple service calls. Others need a proper diagnosis before anything is touched. We’ll tell you exactly what’s going on and what it will cost before any work starts — no guessing, no surprises.

When Repair Makes Sense and When Replacement Does
Not every issue is worth repairing. Here’s how we think about it:
- Repair makes sense when the system is relatively recent, the issue is isolated (a clogged filter, a leaking fitting, a failed valve), and parts are available.
- Replacement makes more sense when the system is aging, repair costs are approaching the cost of a new installation, or the system was never sized correctly for your home to begin with.
We’ll give you an honest read on which direction makes more sense for your situation and we won’t push replacement if repair is the right call. If replacement is the better option, we’ll route you to our Water Filtration System Installation page and walk you through what a new setup would look like.
Common Water Filtration System Problems We Repair
Low Water Pressure or Slow Flow
- A drop in pressure at the kitchen sink or throughout the house often points to a clogged sediment pre-filter, a fouled RO membrane, or a partially closed valve. In Las Vegas and Henderson homes with high mineral content in the water, filters can clog faster than expected — especially if maintenance has been skipped.
Bad Taste or Odor Coming Back
- If your water started tasting like chlorine again, or there’s a musty or sulfur smell, the most common culprits are an exhausted carbon filter, an expired RO membrane, or bacterial growth in a filter housing that hasn’t been serviced in a while. This is one of the most common repair calls we get from North Las Vegas and Summerlin homeowners.
System Leaking at the Housing or Connections
- Leaks at the filter housing, tubing connections, or under-sink fittings are usually caused by worn O-rings, cracked housings, or loose fittings. Left unaddressed, even a slow drip under the sink can cause cabinet damage. We locate the source and fix it cleanly.
RO System Not Producing Water
- If your reverse osmosis tank is empty or filling extremely slowly, the membrane may be exhausted, the tank pressure may be off, or a check valve may have failed. This is one of the more involved RO repairs but is almost always fixable without replacing the entire system.
Water Softener Running Constantly or Not Regenerating
- If your softener is cycling more than it should, failing to regenerate on schedule, or your water has gone hard again, the issue is usually the control valve, a salt bridge in the brine tank, or a resin bed that needs cleaning or replacement. We service all major softener brands serving Las Vegas homes.
Our Repair Process
- Step 1: Describe the problem. Call or text us and tell us what you’re noticing — taste, smell, pressure, leaking, or error codes. A quick description helps us know what to bring.
- Step 2: We diagnose the system. We inspect the full system — filters, membrane, valves, connections, and tank pressure — and tell you exactly what’s causing the issue before any repair starts.
- Step 3: Clear options, upfront. We explain what needs to be done, what it will cost, and whether repair or replacement makes more sense for your specific system. No work starts until you approve it.
- Step 4: Fix it and verify. We complete the repair, run the system, check pressure and flow, and confirm the water quality issue is resolved before we leave.
What Affects the Cost of Water Filtration Repair?
Every home is a little different. Here are the main factors that affect pricing:
- System type — RO membrane replacements, softener valve repairs, and whole-house filter swaps all vary in complexity and parts cost
- How long the issue has been building — a neglected system often has multiple problems by the time it's looked at
- Parts availability — most common brands are well-stocked; older or off-brand systems can sometimes take longer
- Whether the issue is isolated or systemic — a single failed O-ring is a quick fix; a softener with a failed resin bed is more involved

Water Filtration Repair FAQs in Las Vegas, Summerlin, Henderson & North Las Vegas
Expert answers to help you make informed decisions
Q1 How do I know if my water filter needs repair vs. just a filter replacement?
If the only issue is that the filter change indicator is on and your water still tastes fine, a filter swap may be all you need. If the taste, smell, or pressure has changed alongside the indicator, or if there’s a visible leak or the system isn’t cycling correctly, that warrants a proper diagnosis rather than just a filter change.
Q2 My RO water tastes off after I changed the filter. What's wrong?
A few things can cause this — residual carbon fines from a new filter (usually clears after flushing for a few minutes), a membrane that was due for replacement at the same time, or a filter installed in the wrong housing port. If flushing doesn’t clear it within a day or two, call us.
Q3 How often should a water filtration system be serviced in Las Vegas?
Las Vegas water is high in minerals and sediment load, which means filters and membranes can exhaust faster than manufacturer timelines suggest. As a general guide: sediment pre-filters every 6–12 months, carbon filters every 6–12 months, RO membranes every 2–3 years, and softener resin checked every 3–5 years. Higher usage or particularly hard water shortens those intervals.
Q4 My water softener is using salt faster than usual. Is something wrong?
Faster-than-normal salt consumption usually means the control valve is regenerating too frequently or a valve is stuck in the wrong position. It can also indicate a slow internal leak. Either way, it’s worth having checked — a softener running constantly drives up water and salt costs quickly.
Q5 Can I keep using my RO system if the membrane light is on?
Technically yes, but the water is no longer being filtered to the same level. If the membrane is exhausted, dissolved solids, chlorine, and other contaminants are passing through. We’d recommend getting it serviced rather than continuing to use it as-is.
Q6 Do you service all brands of water filtration systems?
We service most major brands of under-sink RO systems, whole-house softeners, and carbon filtration systems common in Las Vegas, Henderson, Summerlin, and North Las Vegas homes. Call or text us with your brand and model and we’ll confirm before scheduling.
Q7 What if my system is old and repair isn't worth it?
We’ll tell you that directly. If the repair cost is approaching the cost of a new system, or if the system was undersized to begin with, replacement is usually the smarter move. We’ll walk you through what a new installation would look like and cross-reference our Water Filtration System Installation page so you can compare options.
Q8 Is there a charge for the diagnostic visit?
Call or text us first — we can often narrow down the likely cause from your description before scheduling anything. For on-site diagnostics, we’ll confirm our service call policy when you contact us.
Q9 Do you serve my area?
Yes. We repair water filtration systems throughout Las Vegas, Summerlin, Henderson, North Las Vegas, Centennial Hills, Enterprise, and surrounding areas. Call or text (702) 908-0953 to confirm your location.
