If the pressure gauge keeps climbing, water is seeping from around the filter tank, or the pool goes cloudy a day after it's balanced, the filter is the first place to look. It's the part of the system that removes dirt, debris, and fine particles from the water, and when it stops doing that, no amount of chemicals will make up for it.

Dog Days cleans filters, replaces worn cartridges, takes DE filters apart and cleans them by hand, and repairs or replaces the filter itself when it's leaking or failing. You'll hear the price before any repair starts.

What goes wrong with a pool filter

Larry doesn't bend on filters. When one lets you down, it's for one of three reasons.

It's dirty: pressure climbs and flow drops

Every filter loads up as it traps debris, and the pressure gauge rises accordingly. Pollen season, oak drop, and a green-pool clean-up all load a filter fast. Past a point, water moves slowly, the pump strains, and the pool stops clearing.

  • check_circleCartridges rinsed, or DE and sand filters backwashed, when the pressure calls for it
  • check_circlePressure noted after cleaning, so the next rise means something
  • check_circleSkimmer and pump baskets checked, since they protect the filter

It's worn: it's clean, but the water still isn't

Cartridge pleats flatten and tear, and DE grids rip or clog for good. A worn filter can look clean and still let fine particles straight back into the pool, and no amount of brushing makes up for it.

It's broken: leaks, cracks, and valves

Water around the base, a drip from the band that holds the tank together, a multiport valve that leaks to waste, a stuck air-relief valve, or a gauge that doesn't read. Most of these are parts. A cracked tank is a replacement.

  • check_circleMultiport and backwash valves repaired or replaced
  • check_circleWhole filter replaced when the tank is cracked, or parts aren't made anymore

The yearly filter service, and why it isn't optional

Every weekly customer is told this on day one: once a year, at the end of spring after pollen season, every cartridge filter gets new cartridges, and every DE filter gets split open, cleaned by hand, and its grids inspected for damage. It's added to your invoice, and Larry treats it as non-negotiable. Sand filters work differently and aren't part of it.

routeThe Process

How a filter repair or cleaning works

1
call

1. Tell us what you're seeing

The pressure reading, a leak, or water that won't clear. If you know whether it's a cartridge, DE, or sand filter, mention it.

2
search

2. We open it up

We check the media, the tank, the O-rings, the valves, and the gauge, and look at what the filter is catching.

3
request_quote

3. You hear what it needs

A cleaning, new cartridges, a part, or a new filter, with the price. Nothing gets done until you've said yes.

4. The work

Cleaned, rebuilt, or replaced, then put back together with fresh lubricant on the O-rings.

5

5. Back online

We restart the system, bleed out the air, check for leaks, and note the clean pressure, so you know what normal looks like.

info

Sand filters are the one type we don't open up. We'll replace a multiport valve or a pressure gauge, but by the time a sand filter needs work inside, the laterals are sitting under hundreds of pounds of wet sand and, in Larry's experience, something is broken, so we replace the filter instead.

What filter service doesn't include:

  • remove_circleWe don't do leak detection. If the water loss isn't at the filter or the equipment pad, we'll coordinate detection with a specialist we trust.
  • remove_circleWe don't service filters on above-ground pools, freestanding hot tubs, or commercial pools.

How filter work is priced

Whether the cartridges or grids clean up or have to be replaced determines most of it. Larry quotes once he's opened the filter. The rest comes down to:

filter_alt01

Filter type and size:Cartridge sizes and DE grid sets vary a lot in cost.

compare_arrows02

Cleaning or replacing:Media that cleans up is a smaller job than media that has to go.

settings03

Parts:O-rings and gauges are small; a valve or a tank is not.

swap_horiz04

Replacement filter:Sized for your pool and pump, with the plumbing to match.

receipt_long

For weekly customers, the yearly filter service is added to your invoice. Any repair over $50 waits for your OK, with no hidden fees. Weekly customers' small wear parts under $50 go on the next invoice; everyone else approves every repair.

A filter leak, fixed on the spot

“We noticed leaking around the filter and called Larry based on someone else's recommendation. Even though we hadn't used him before he managed to work us into his schedule the same day we called him. It didn't take him long to diagnose the problem and he was able to fix it on the spot.”

A new filter system, and a pump left alone

“He recently replaced our malfunctioning filter system. At every step along the way, with this and other jobs, he has been knowledgeable and the consummate professional. He gave me choices on pricing levels and styles and saved me money by telling me that my loud but functioning pool pump did not have to be replaced.”

Kept running, then replaced right

“They've also tried to help me keep my filter limping along when things were tight. Now that the filter has finally given up the ghost, I don't need to worry about the quality of replacement work, and I don't with them”

Pool filter questions

?How do I know when my filter needs cleaning?expand_more
Watch the pressure gauge. Note the reading right after a cleaning; when it climbs well above that, the filter is loaded. Weak returns and a cloudy pool are other signs.
?How often do cartridges need replacing?expand_more
For our weekly customers, once a year, at the end of spring after pollen season. A cartridge that's torn or flattened may need replacing sooner.
?Why is the yearly filter service required?expand_more
Because the filter is what keeps the water clean, and a worn one can't do it no matter how good the weekly visit is.
?Why is there gray dust on the pool floor after a backwash?expand_more
Gray dust on the floor after a backwash or a cleaning usually means a torn grid or a manifold problem inside a DE filter. It needs opening up.
?Why is water leaking around my filter?expand_more
The usual causes are the tank O-ring, the clamp band, the drain plug, or a valve. Most are parts. A crack in the tank means a new filter.
?Should I clean my own filter?expand_more
You can rinse a cartridge between visits if you're comfortable doing it. Turn the power off at the breaker, open the air-relief valve to release the pressure, and never loosen the clamp while the tank is under pressure. When you restart the pump, stand clear of the filter. If you're a weekly customer, tell your technician and make sure the pump and valves are set to their normal settings. Opening a DE filter is better left to us, and so is any filter whose O-ring or clamp gives you trouble, because a badly seated O-ring leaks.
?Do you replace whole filter systems?expand_more
Yes, when a filter is cracked, or parts aren't made for it anymore. See Pool Equipment Upgrades if you're choosing a new one.
