What it is
What Service & Maintenance does for your home
A water treatment system isn't install-and-forget. Filters load up, resin exhausts, membranes foul, and valves drift out of calibration — and the water quality quietly slips. Our service and maintenance plan keeps every system we install running at peak, and we service most major brands we didn't put in too. Annual filter changes, salt refills, system tune-ups, and sanitization on a set schedule, done by the same licensed, insured KC technicians who installed it.
The signs
Signs your home needs Service & Maintenance
If any of these sound familiar, a free in-home water test will tell you whether this is the fix.
- Your softener ran out of salt and now the scale is back
- Filters past their service life that let chlorine and sediment through again
- A control valve that's drifted out of calibration, regenerating too often or not enough
- An RO membrane that's fouled and your drinking water tastes flat again
- A system from another company whose installer vanished after the sale
How it works
Our Service & Maintenance process
Four steps from free test to lifetime-backed system — no pressure, no surprises.
- 1
System inspection
We check flow rate, pressure, valve cycles, salt level, and media condition, then test the output water against your system's spec to see what's drifted.
- 2
Filter & media service
We swap spent carbon and sediment filters, refresh or replace exhausted resin, and replace RO pre/post-filters and membranes on their schedule.
- 3
Tune-up & sanitization
We recalibrate the control valve, sanitize the brine tank and resin bed, and flush the system so your water runs clean from the first gallon after service.
- 4
Service report
You get a written report of what we found, what we changed, and when your next service is due — so it's never a surprise.
American-made parts
What goes into a Cathcart system
Every system is built with American-made components — control valves from Wisconsin, tanks from Ohio, resin from New Jersey, and carbon from Ohio.
OEM-spec replacement filters
We stock carbon blocks, sediment filters, and RO membranes that meet or exceed the original system's spec — no generic substitutes that underperform.
Softener salt & resin
Clean, high-purity softener salt delivered to your brine tank, plus ResinTech replacement resin when a bed is exhausted beyond recharge.
Valve & parts calibration
Genuine Hanskraft and Enpress parts for the systems we install, so a tune-up restores factory performance rather than a patch job.
Control Valve — Hanskraft (Wisconsin) · Tank — Enpress LLC (Ohio) · Carbon — Jacobi Group (Ohio) · Resin — ResinTech (New Jersey)
Is this you?
When to call us about Service & Maintenance
- Your softener's brine tank is empty and you keep forgetting to refill it
- Chlorine taste or smell is creeping back into your water
- Your water pressure has dropped since the system was installed
- The control valve regenerates at odd hours or runs constantly
- It's been over a year since anyone looked at your system
- Your system came with the house and you've never had it serviced
Pricing, honestly
No surprises, no high-pressure sales
Service is billed per visit or bundled into an annual plan — we'll quote both after inspecting your system so you can choose. There's no charge to tell you what your system needs, and we service most major brands even if we didn't install it. If a part is covered under our lifetime or 5-year warranty, that repair is on us. Transparent pricing, no surprise add-ons.

Real Kansas City reviews
What service & maintenance customers say
“Bought a house with a softener already in and no manual. Cathcart serviced it, got it running right, and put me on their annual plan. Water's been perfect since.”
“The annual service is worth it just to not think about salt anymore. They show up, swap the filters, refill the brine tank, and leave a clean report. Easy.”
“Our RO membrane was overdue and the water tasted off. They caught it on the annual visit, replaced it under warranty, and we were back to great water the same day.”
