Grand Rapids / Rio Grande / Swift Current Drain Cap
Couldn't load pickup availability
Replacement external drain cap with gasket for Canadian Spa portable hot tubs. The cap fits onto the end of the drain pipe on the outside of the spa, and the gasket keeps the seal watertight between water changes.
Drain caps are easily misplaced when draining the spa – and a lost cap means a spa you can't refill. Keep a spare with your chemicals so a £5 part never ruins a weekend.
Key features
- Includes sealing gasket
- Fits the external end of the drain pipe
- Genuine Canadian Spa Company replacement part
- Pairs with the internal drain plug (sold separately)
Compatibility
Fits the Canadian Spa Grand Rapids, Rio Grande and Swift Current portable spas.

Buying and support guide
We supply the Grand Rapids / Rio Grande / Swift Current Drain Cap with clear specs and UK support. Before you order, check it suits your spa model, size, connector type, power supply and access. This helps you avoid delays and returns.
Replacing a part? Match it to your spa's model and year where you can. For pumps, control packs, heaters, jets, covers, filters, topsides and plumbing, check the part number and connection type. Compare delivery time, warranty and support as well as price.
Running costs matter as much as the price you pay. Energy use, insulation, cover condition, filters and water care all affect long-term value. Replacing worn parts early and keeping the water moving and filtered can save on repairs.
Looking for a whole new tub rather than a part? Compare hot tubs, swim spas and saunas by seating, hydrotherapy, who will use it and the space you have.
