Boshart BSC Full Port Sump & Sewage Check Valve with 2 Boots

The Boshart BSC Sump & Sewage Check Valve is a full port check valve built for sump pump and sewage ejector discharge lines, available in 1-1/2" and 2" sizes to match common pump discharge and riser piping. Every size in the BSC line ships complete with 2 boots for a fast, gasketed connection to the pump discharge pipe and the riser pipe on either side of the valve. The full port flapper design opens 100% for unrestricted flow through the valve body, and the flapper seats on a 15° angle rather than sitting flat, which reduces the slam and water hammer that occurs when the pump shuts off and the flapper drops closed. The angled seat also helps keep solids and debris from building up on the seating surface or getting trapped under the flapper, so the valve continues to seat properly cycle after cycle. This is rough-in, behind-the-wall (or below-the-floor/in-the-pit) plumbing hardware intended for installation by a plumber or contractor on sump basin discharge piping and sewage ejector discharge piping in either the 1-1/2" or 2" size, not a decorative fixture.

Key Features

  • Trade Size Range: Available in 1-1/2" and 2" sizes to fit common sump and sewage discharge piping.
  • Full Port Design: The flapper opens 100% for unobstructed flow through the check valve body, minimizing restriction on sump and sewage discharge lines.
  • Angled Flapper Seat: The flapper seats at a 15° angle, which reduces water hammer noise and shock at pump shut-off compared to a flat-seating flapper.
  • Debris-Resistant Seating: The angled seat design helps prevent debris from building up or becoming trapped in the valve, supporting a consistent, proper seal over repeated pump cycles.
  • Blow-Out Proof Gasket: A nylon reinforced gasket design is used at the flapper/seat interface to resist blow-out under the pressure surges typical of sump and sewage pump discharge.
  • Includes 2 Boots: Each check valve ships complete with 2 boots for connecting the valve to the discharge pipe on the pump side and the riser pipe on the outlet side.
  • Country of Origin: Manufactured in Canada.

Why Boshart?

Boshart engineers this check valve with a full port, angled-seat flapper and a nylon reinforced, blow-out proof gasket to hold up against the repeated open/close cycling and pressure surges of sump and sewage pump operation, across both the 1-1/2" and 2" sizes in the BSC line. Supplying every valve complete with 2 boots simplifies the installation on both the pump-side and riser-side connections, making it a practical choice for plumbers and contractors handling rough-in sump and sewage discharge work of any size in this range.

Boshart BSC-150-SB – Frequently Asked Questions

1) What sizes does the Boshart BSC sump and sewage check valve come in?
Two trade sizes: 1-1/2 inch (BSC-150-SB) and 2 inch (BSC-200-SB). Match the size to the pump discharge and riser piping you are tying into, not to the basin. Most 1/3 to 1/2 HP sump pumps discharge at 1-1/2 inch, while sewage ejectors are commonly 2 inch.
2) Do I need to buy couplings separately to install this check valve?
No. Every BSC valve ships with 2 boots, one for the pump-side discharge pipe and one for the riser pipe on the outlet side, so both connections are covered out of the box. You supply the pipe and the clamps per your local practice.
3) Will this check valve stop the banging noise in my sump discharge line when the pump shuts off?
That bang is water hammer from a flapper dropping flat onto its seat. The BSC flapper seats on a 15 degree angle instead, which softens the closing impact and cuts the slam at pump shut-off. It reduces the noise rather than eliminating it, but it is a real improvement over a flat-seating check valve on the same line.
4) Can I use the Boshart BSC to replace the check valve on an existing sump pump swap?
Yes, pump replacement and retrofit work is one of its listed applications. Because it comes with both boots, it reconnects to the existing pump discharge and the existing riser without hunting for separate couplings. Confirm you are ordering the size that matches your existing discharge pipe, 1-1/2 inch or 2 inch.
5) Is a full port check valve worth it on a sewage ejector line, or will a standard one do?
On sewage and solids-bearing discharge, full port matters. The BSC flapper opens 100 percent so the bore through the valve body is not reduced, which keeps flow velocity up and avoids a restriction where rags and solids would hang up. A reduced-port check valve on an ejector line is a common cause of clogging and lost pump capacity.
6) Will the gasket blow out under the pressure surge when a sewage pump kicks on?
The flapper and seat interface uses a nylon reinforced, blow-out proof gasket specifically for the pressure surges that sump and sewage pumps produce on start-up. That reinforcement is the difference between this and a plain rubber flapper that deforms after repeated cycling.
7) Will debris keep this check valve from sealing over time?
The 15 degree seat is angled partly for that reason. Solids and grit tend to wash past rather than settle on the seating surface or wedge under the flapper, so the valve keeps seating properly cycle after cycle. On a flat seat, debris collects on the horizontal face and holds the flapper open, which is how you end up with water draining back into the pit and the pump short-cycling.
8) Can I standardize on one check valve across sump pits and sewage ejectors in a multi-family building?
The BSC line covers both duties, sump pump discharge and sewage ejector discharge, in the same valve design across its 1-1/2 inch and 2 inch sizes. For a property manager or MRO stockroom that means two part numbers, BSC-150-SB and BSC-200-SB, cover most basin and ejector discharge lines in the portfolio, with the boots already in the box so there is no separate coupling SKU to stock.
9) Is this Boshart check valve made in North America, and does it carry a Prop 65 warning?
Manufactured in Canada, and no Prop 65 warning applies to it. That matters for institutional and government buyers working to domestic-content or disclosure requirements on their purchase orders.
