Sump Pump Installation in Calgary — Spec, Install, and Backup

Our standard pricing: replacement pump in an existing pit (ProFlo 1/2 HP cast-iron) is around $504. New sump pit + pump from scratch (cut the slab, install basin, pump, discharge, and check valve) is around $2,000. Battery backup pump add-on to an existing primary is $900–$1,500 including battery. Backwater valve install is a separate quote — typically $2,500–$4,500 depending on accessibility. All quotes are in writing with line items — no surprise charges at the end.

Cast-iron pumps in a properly-sized pit typically last 10-15 years. Plastic-impeller box-store pumps in undersized pits or high-cycle situations can fail in 3-5 years. Battery backup pumps fire much less often than primaries, so the pump itself can last 15-20 years — but the battery needs replacement every 4-5 years regardless of use.

If a flooded basement would cause meaningful damage (finished basement, drywall, flooring, stored items), yes. The storms that push your sump system to its limit are the same ones that knock out power. We've responded to too many flooded basements where the homeowner had a working primary pump — but no power and no backup. For unfinished basements with concrete floors and nothing valuable down there, the case is weaker.

Different problems. Sump pump handles GROUNDWATER coming through your foundation walls and weeping tile. Backwater valve handles MUNICIPAL SEWER BACKUP — when city sewers overload and try to push sewage back into your home through floor drains and basement fixtures. Calgary's 2013 flood drove home that you need both for properties at risk. We can install one or both depending on what your home actually needs.

Neither, ideally. Tying into the city storm drain requires a permit and the city often denies for sump discharge. Dumping straight onto the lawn at the foundation just re-routes water back through your weeping tile. The right approach is a discharge run that takes water at least 6 feet from the foundation, slopes away from the house, and ends at a splash block or extended downspout that disperses the flow.

The pump itself is below frost line in the pit — it won't freeze. The discharge line is the freeze risk. We slope discharge so water drains out after each cycle (nothing sitting in the pipe to freeze), use flex pipe at the exit point that can flex with frost movement, and avoid long horizontal exterior runs that pool water. If your existing discharge has frozen and back-loaded the pump, we re-route it during the install.

Primary and battery-backup pumps plug into a standard outlet — we don't need an electrician for that. If your sump pit doesn't have an outlet, or the outlet is shared with too much else and trips when the pump kicks on, we can install a dedicated GFCI circuit (sub-contracted to a licensed electrician — we coordinate, you only deal with one person). For most installs, electrical is not a separate cost.
