Cartridge, DE or sand — we take the filter apart, clean it the way that type needs, check it for damage and record the clean pressure, so you know when the next one is due.
Clean it when the pressure gauge reads 8–10 psi above its clean reading — the rule in the filter makers’ manuals. On Lewisville’s municipal water most cartridges want a clean every 4–6 months. Sand and DE filters are backwashed at the same rise and taken apart when a backwash stops bringing the pressure down.
We price a filter clean at the visit: it is the on-site time for your filter type plus only the parts it needs, such as a tank o-ring, filter cleaner or a DE recharge. A new cartridge, grid or sand is quoted only when the old one is done.
No backwash setting at all means a cartridge filter: the elements come out and every pleat is hosed clean. If you add white powder through the skimmer after a backwash, it is DE — backwashed, taken apart to clean the grids, then recharged with fresh DE. A multiport valve and no powder means sand, which is backwashed and, when that stops working, chemically cleaned.
Yes: turn the pump off and open the air relief so the tank is not under pressure, then pull the cartridge and hose it from the top down, pleat by pleat — never with a pressure washer, which tears the fabric. Soak it in filter cleaner if it is greasy or crusted, and lube the tank o-ring before you close it. Book us if the pleats are torn, the end caps are loose, or the pressure stays high after a clean.
On site, a cartridge clean takes about an hour, a DE clean and recharge about 1¼ hours, and a sand filter service about 45 minutes. That is the whole visit: shut down, clean, check for damage, reassemble and record the new clean pressure.
A filter clean is its own visit: we shut the system down, clean the cartridge, DE grids or sand bed the way that filter needs, check it for damage and put it back with the new clean pressure recorded.
What we don't do (just so you know)
Find yours by the first line on each card, then see what we do, how long it takes and what it costs.
How to tell: No backwash setting at all — a tank that opens at a clamp or lid, with pleated fabric elements inside.
How we clean it
How often: When the gauge reads 8–10 psi above its clean reading — for most pools every 3–6 months.
Torn or flattened pleats, loose end caps, or a clean that no longer brings the pressure down mean new elements.
How to tell: A backwash valve, and white powder (diatomaceous earth) you add through the skimmer after a backwash.
How we clean it
How often: Backwash at 8–10 psi over the clean reading and add back DE; take it apart and clean the grids when a backwash no longer brings the pressure down.
DE blowing back into the pool means a torn grid or a cracked manifold — recharging over it just wastes the bag.
How to tell: A multiport valve with Filter, Backwash and Rinse settings, and no powder to add.
How we clean it
How often: Backwash at 8–10 psi over the clean reading. The sand itself usually lasts 5–7 years on city water and 4–5 years on well water.
Sand in the pool, very short runs between backwashes, or sand past its years mean new sand or laterals — a repair visit.

The 8–10 psi rule is the one in the filter makers’ owner’s manuals.
Most high-pressure, cloudy-water calls are a clean. These are the signs that it is something more.

Lewisville is a major DFW suburb with over 115,000 residents spread across diverse neighborhoods ranging from established communities built in the 1980s to brand-new master-planned developments. The city sits along Lewisville Lake, one of DFW's most popular recreation areas, and benefits from excellent transportation access via I-35E and the DART rail system. The pool market in Lewisville is massive and varied — Castle Hills and other newer developments feature modern pools with premium equipment, while established neighborhoods along Valley Ridge and throughout central Lewisville contain thousands of older pools that benefit from regular professional maintenance and equipment updates. Lewisville's proximity to the lake means seasonal moisture and humidity can affect algae pressure, while the city's mature tree canopy creates leaf management challenges in many neighborhoods. The sheer number of pools in Lewisville combined with the diversity of ages and equipment types requires a service provider with deep technical knowledge and flexible service approaches. Our team handles everything from basic weekly chemical maintenance on newer salt pools to comprehensive service on 30-year-old plaster pools with original equipment. Located just 10 miles from our Northlake headquarters, Lewisville is efficiently served with multiple weekly routes.
Lewisville is served by municipal water from the City of Lewisville system, sourcing from Lewisville Lake and the DFW water supply network. Water quality is good with moderate mineral content (300-400 ppm TDS). The proximity to Lewisville Lake means seasonal algae pressure can be higher, particularly in summer and early fall. Municipal water is generally favorable for pool maintenance with consistent chemistry year-round.
Lewisville has the widest diversity of pool types in our service area. Established neighborhoods (1980s-2000s) contain classic plaster pools with sand filters and single-speed pumps — many approaching or past equipment replacement age. Newer communities like Castle Hills feature modern installations with pebble finishes, cartridge filtration, variable-speed pumps, and smart automation. Mid-range neighborhoods often have pools in the 15-20 year old range that benefit from targeted equipment upgrades. Pool sizes range from compact 8,000-gallon backyard pools to large 30,000+ gallon installations.
