Quick answer: The Jackel SF20 is the best overall sump pump basin — a solid-wall, 18 in. x 22 in. structural-foam liner that fits the majority of residential pits and keeps groundwater out except through its single inlet hole. The Jackel SF20-DR is the identical basin pre-drilled with perforations for homes with a high water table or no perimeter drain tile, and the Jackel SF22 steps up to 18 in. x 24 in. for heavier inflow or a pump that’s cycling too often. None of these include a pump, lid, or float switch — a basin is the liner the rest of your sump system sits inside, sold and replaced separately.
Every sump pump article — including our own — talks about horsepower, GPH, and float switches, and almost never mentions the plastic bucket all of it sits inside. That’s a gap, because the basin itself makes two decisions for you before a pump ever turns on: whether groundwater reaches the pit through one controlled inlet or through dozens of wall holes, and how much water the system holds between pump cycles. Get either one wrong and you can end up chasing a “bad pump” problem that was actually a basin problem the whole time.
Our top picks at a glance

| Jackel SF20-DR | Best for high water table | 18 in. x 22 in., ~20 gal. | Perforated | ~$43 |
| Jackel SF22 | Best for heavy inflow | 18 in. x 24 in. | Solid | ~$55-65 |
1. Jackel SF20 — Best Overall
Jackel SF20 Sump Basin
- Solid injection-molded polyethylene walls mean groundwater and silt only enter through the basin's own inlet hole, not through dozens of uncontrolled holes in the sides — the right choice when your home already has perimeter drain tile doing the real work of routing water to the pit.
- 18 in. x 22 in. is the single most common residential basin size, so it's the safe default when you're replacing a basin and don't have an unusual pit or local code minimum to work around.
- Metal cover-mounting inserts are molded into the rim, so it accepts a standard bolted cover — including the [sump pump covers](/best/best-sump-pump-cover/) we've already tested — without drilling your own mounting holes.

Buy this one if your current basin is cracked, collapsed, or missing and you don’t have a specific reason to go perforated or oversized — it’s the default that fits the most pumps and the most pits.
2. Jackel SF20-DR — Best for High Water Table
Jackel SF20-DR Perforated Sump Basin
- Factory-drilled wall holes let groundwater enter directly from the surrounding soil, instead of relying on a single drain-tile inlet to keep up — the right call if your house has no perimeter drain tile or sits on ground that's wet even without rain.
- Same 18 in. x 22 in. shell, same cover fitment, and the same roughly $43 price as the solid SF20 — choosing perforated vs. solid costs nothing extra, it's purely a question of how water actually reaches your pit.
- Not the right pick if your drain tile already works well: a perforated basin lets more silt and fine soil into the pit along with the water, which means more sediment buildup at the pump inlet over time.
Choose this over the solid SF20 only if you know water reaches your pit from the surrounding soil, not just through a drain-tile inlet pipe — in a working drain-tile system, the holes add silt without adding any real drainage benefit.
3. Jackel SF22 — Best for Heavy Inflow
Jackel SF22 Sump Basin
- The extra 2 in. of depth over the SF20 holds meaningfully more water between pump cycles — useful if your current pump short-cycles in a smaller basin, which wears out the float switch and motor faster than the same pump running in a properly sized pit.
- This is a basin-sizing fix, not a horsepower fix: as our best sump pump guide covers, oversizing the pump itself to "solve" short-cycling usually makes it worse, while a bigger basin genuinely spaces cycles out.
- Still solid-wall construction (not perforated) — if you also have a high-water-table problem on top of heavy inflow, there isn't currently a drilled version of this larger size from the same line, so plan on adding your own inlet holes sized to your drain tile.
Step up to this size if an 18 in. x 22 in. basin leaves your pump cycling on and off every minute or two during heavy rain — that’s a basin-capacity problem first, and a pump problem only if the basin fix doesn’t solve it.
Solid vs. perforated: the decision that actually matters
Most basin shopping focuses on size, but the solid-vs-perforated choice has more effect on how your whole system behaves. A solid-wall basin only takes on water through its molded inlet hole, which is designed to connect to perimeter drain tile running around your foundation footing — if that tile system is doing its job, the basin stays relatively clean and the pump only deals with the water the tile actually routes to it. A perforated basin skips that gatekeeping: water (and the silt suspended in it) enters through dozens of drilled holes straight from the surrounding gravel bed, which is what you want when there’s no drain tile to rely on, or the water table is high enough that water needs multiple entry points to keep the pit from building pressure underneath your slab. Buying the wrong one doesn’t make the basin fail outright, but it does mean either starving a perforated basin of water it was built to admit, or feeding a solid basin’s single inlet more silt than drain tile alone would deliver.
The bottom line
The Jackel SF20 is the basin to buy for a standard replacement with working drain tile — solid, 18 in. x 22 in., and compatible with the covers and pumps most of this site already recommends. Switch to the Jackel SF20-DR only if groundwater reaches your pit without drain tile’s help, and step up to the Jackel SF22 if cycling frequency — not pump horsepower — is your actual problem. Whichever basin you land on, pair it with a sealed sump pump cover to stop radon and humidity, and see our sump pump maintenance guide for how often to check the pit itself, not just the pump sitting in it.
