Water Filter Replacement & Maintenance in San Diego County

Reverse Osmosis Filter Changes & RO Service

Reverse osmosis systems need routine maintenance to keep drinking water tasting clean and the system operating correctly.

For standard under-sink RO systems, service may include:

• Sediment prefilter replacement

• Carbon prefilter replacement

• Post-carbon filter replacement

• RO membrane inspection or replacement when appropriate

• System flushing and sanitization

• Storage tank pressure check

• Faucet and drain-line inspection

• Leak check under the sink

• Flow and performance check

• TDS testing when appropriate

Your RO membrane usually lasts longer than the regular filters—but only if the prefilters are changed on time and the system is maintained properly.

If your RO water is slow, tastes off, smells strange, is leaking, or has been ignored for a few years, we can inspect it and give you a straight answer about whether it needs filters, a membrane, a repair, or replacement.

Whole-House Filter & Carbon System Service

Whole-house systems protect more than drinking water. They can affect showers, fixtures, appliances, tankless water heaters, ice makers, laundry, and the plumbing throughout your home.

Kraken Water Systems services systems such as:

• Sediment filters

• Carbon block and granular activated-carbon filters

• Whole-house cartridge filters

• Big Blue-style filter housings

• Backwashing carbon systems

• Specialty media filters

• Iron, manganese, sulfur, or well-water treatment filters

• Commercial filtration systems

• Ice-machine and coffee/espresso filtration

Depending on the equipment, service may involve cartridge replacement, backwashing checks, media inspection, valve programming, leak inspection, pressure checks, and performance testing.

How Often Should Filters Be Changed?

There is no honest one-answer schedule for every system.

The right interval depends on:

• The type of system

• The filter size and capacity

• Household water use

• Water quality

• Sediment levels

• Chlorine or chloramine levels

• Whether the system serves drinking water, the entire home, or commercial equipment

• Manufacturer recommendations

• Previous maintenance history

Many reverse osmosis prefilters and postfilters are commonly changed every 6 to 12 months. RO membranes often last longer, but their condition should be checked rather than guessed. Whole-house filters may need service more or less often depending on water use and what the filter is treating.

If you are unsure when your filters were last changed, that is usually a good sign it is time for a professional check.

Frequently Asked Questions

Can I change my own water filters?

In some cases, yes. But professional service makes sense when you are unsure what filters fit, when the system is leaking or underperforming, when maintenance has been neglected, or when you want the system inspected and tested at the same time.

How do I know if my RO membrane needs replacement?

Slow production, poor water quality, rising TDS, odd taste, and missed maintenance can all be signs. The membrane should be evaluated as part of a proper RO service—not replaced automatically just because someone wants to sell a part.

Why is my RO faucet flowing slowly?

Slow flow can be caused by loaded filters, a worn membrane, low storage-tank pressure, a clogged faucet, restricted tubing, a failing shutoff valve, or another issue. We can diagnose the actual cause.

Do you service Kinetico and other proprietary systems?

We can inspect and service many systems and help identify the correct maintenance path. Some proprietary equipment uses specialized components, but we will explain your options clearly before doing any work.

Can you remind me when my system is due for service?

Yes. Kraken Water Systems can help keep track of your maintenance schedule so filter changes and annual checks do not get forgotten.

Keep Your Water System Working the Way It Should

Do not wait until your water tastes bad, the RO faucet barely flows, or a neglected filter starts leaking.

Kraken Water Systems can inspect your system, change the correct filters, test performance, and help protect the equipment you already own.
