Pool Filter Repair. Clear Water Again.

Your filter is the reason your water stays clean. When it fails, you notice fast. We fix it so you do not have to think about it.

A Bad Filter Means Bad Water. Every Time.

Your pool filter removes dirt, debris, bacteria, and microscopic particles from thousands of gallons of water every day. When it is not working right, nothing else matters. Your chemicals will not hold. Your water turns cloudy. Algae gets a foothold. And you end up spending more money on chemicals trying to compensate for a filter that is not doing its job.

We repair all three filter types: DE (diatomaceous earth), cartridge, and sand filters. Each one fails differently, and each one requires a different approach. We diagnose the actual problem, not just the symptom.

When your pressure gauge is spiking, your water will not clear up, or you are finding DE powder or sand back in the pool, those are all signs of specific internal failures that we can pinpoint and repair. We serve homeowners across Riverside County and Orange County.

Signs Your Pool Filter Needs Repair

Filter problems do not always announce themselves with a dramatic failure. Sometimes it is a slow decline that you do not notice until the water is already suffering:

High Filter Pressure

When the pressure gauge reads 8-10 PSI above your clean baseline, the filter is struggling. Dirty grids, worn cartridges, or channeled sand all restrict flow and push pressure up. If cleaning does not bring it down, internal parts need attention.

Cloudy Water That Will Not Clear

You keep adding clarifier and shocking, but the water stays hazy. That usually means the filter is passing particles instead of catching them. Torn DE grids, cracked cartridge pleats, or a bad multiport valve gasket let dirty water bypass the filter media entirely.

DE Powder or Sand in the Pool

If you see white powder on the bottom of your pool after backwashing, your DE grids are torn. If sand is coming through the returns, a lateral in your sand filter is broken. Both are straightforward repairs we handle regularly.

Leaking Filter Tank or Valve

Water leaking from the filter housing, the multiport valve, or plumbing connections. Common culprits include a cracked tank, bad belly band gasket, or a worn spider gasket in the valve. All repairable without replacing the whole filter.

We Work on Every Filter Type

Every filter type has its own failure points and repair requirements. We know each one inside and out because we service them every day.

DE Filters: The best filtration available, but the most complex internally. We replace torn grids, rebuild manifolds, replace standpipes, and repair multiport and push-pull valves. If your DE filter is blowing powder back into the pool, we find exactly which grid failed.

Cartridge Filters: Popular for their low maintenance. When the cartridge is worn, cracked, or collapsed, no amount of hosing will restore it. We inspect cartridge condition and replace when needed, making sure the housing seals properly.

Sand Filters: Simple and durable, but the sand channels over time and the laterals crack. We replace filter sand, swap broken laterals, and rebuild multiport valves so backwashing actually works again.

Here's How We Handle It

Step 1

Tell Us What Is Going On

Fill out our form with your filter type, the symptoms, and your zip code. Include the pressure reading if you can. We will reach out to schedule a diagnostic visit.

Step 2

Inspect & Diagnose

We open the filter, inspect the internals, check the valve, test the pressure, and identify exactly what failed. You get a clear diagnosis and a quote before we proceed.

Step 3

Repair & Verify

We complete the repair, reassemble the filter, and run the system to confirm pressure is normal and water clarity improves. You get a filter that actually works again.

Why Homeowners Trust Our Filter Repairs

We Know Hard Water Filters

High mineral content in the local water wears out filter media faster than coastal areas. We understand the water conditions and recommend maintenance intervals that actually keep your filter effective.

Repair First, Replace Only If Necessary

Some companies want to sell you a brand new filter when all you need is a $40 gasket. We repair what can be repaired and only recommend replacement when the tank is cracked or the cost to repair exceeds the value of the unit.

Caught Early on Weekly Service

For clients on our weekly pool maintenance plan, filter pressure gets checked every visit. Rising pressure or reduced flow gets flagged and addressed before it becomes an emergency. Prevention beats repair every time.

No Hidden Charges

We quote the repair after diagnosis, parts included. No surprise line items, no inflated labor charges. You approve the price before we start the work.

DE powder kept blowing back into the pool. They found two torn grids, replaced them, and reassembled everything. Filter pressure is perfect now.

Amanda Walsh
Corona, CA

Our filter tank had a hairline crack that was leaking slowly. They spotted it right away, replaced the tank, and had the system running the same day.

Ryan Patel
Anaheim Hills, CA

High filter pressure was making the pump work overtime. They replaced the internals and the multiport valve. System runs smooth and quiet now.

Heather Brooks
Riverside, CA

Sand was getting into the pool every time I backwashed. They found cracked laterals at the bottom of the filter, replaced them all, and no more sand.

Glen Sawyer
Villa Park, CA

Multiport valve was leaking out the waste port constantly. They rebuilt the valve with a new gasket and spring, and it seals perfectly in every position now.

Mindy Jacobs
Orange, CA

Our cartridge filter housing was warped and would not seal. They replaced the lid and o-ring, and the pressure holds steady. No more leaks on the equipment pad.

Roberto Fuentes
Corona, CA

Filter pressure would spike to 30 PSI within days of cleaning. They found a collapsed internal manifold. Replaced it and the filter holds clean pressure for weeks now.
