If so, then no, this is not the piece you want. If you look at the photo of the piece, the upright 'leg' of the T as it's shown here, holds a swinging flap, which sits across and regulates the flow in the through-pipe (allows liquid freely through in one direction, 'non-return' or blocked if the flow is the opposite direction) **Q: To ensure I have the correct fitting, my waste pipe is 40mm diameter. Does this non-return valve fit as the dimensions shown suggest it won't?** A: I have fitted mine to my 40mm waste pipe. Mine is push fit but it will also fit 40mm solvent pipe. **Q: Could this be used on the outlet flow of a macerator?** A: Yes. I have mine connected to a saniflow macerator although for kitchen use only, I have no experience of it being used in a WC system. I use it in a kitchen sink since the one valve system used is not very good when disconnecting the saniflow pump for repair/maintenance. **Q: Is it possible to buy the rubber seal separately as it wears after a period requiring the whole fitting to be bought just to get a new . Thanksseal** A: No you cant buy, but you can make one get a piece of gasket rubber and cut ring out. Dont pour harsh drain cleaners down pipe, that will perish seal, ok ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic solution to a backflow problem in the shower *by D***N on 8 February 2026* Excellent product did the job ### ⭐⭐⭐⭐⭐ works well *by A***R on 30 August 2024* fitting is simple ### ⭐⭐⭐⭐ Fits *by F***R on 12 March 2026* Useful ## Frequently Bought Together - McAlpine T28M-NRV Multifit in-Line Non-Return Valve, White - Merriway BH02915 Waste Compression 90 Degree Bend, 40mm, White - Merriway BH02916 Waste Compression Tee Connector, 40mm , White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/48962819-mcalpine-t28m-nrv-multifit-in-line-non-return-valve-white](https://www.desertcart.id/products/48962819-mcalpine-t28m-nrv-multifit-in-line-non-return-valve-white) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-09*
