Straightforward Saniflo Installation

Saniflo units are true lifesavers when it comes to adding bathrooms, kitchens, cloakrooms, or en-suites to spaces where traditional drainage and gravity don’t cooperate.

While we strongly recommend professional plumber assistance for a seamless setup, following Saniflos 10 golden rules can help ensure that all Saniflo installation is carried out correctly.

 10 Golden Rules of Saniflo Installation

 

1. Choose the Right Pipework

Ensure discharge pipework is copper or rigid solvent weld plastic, avoiding ‘pushfit’. Maintain a 1% fall on horizontal runs for optimal performance.

2. Optimize Gradients

Place vertical lifts as close to the run’s start as possible, with a minimum 1% fall from the highest point. The proximity of the vertical lift to the unit enhances pump efficiency.

3. Smooth Out Bends

Use smooth, long-radius bends for all pipe sizes; avoid tight radius bends. Support all pipework according to the manufacturer’s recommendations.

4. Mind Entry Pipes:

Pipes entering the Saniflo should have a gravity fall of 3% to facilitate proper function.

5. Correct Pipe Sizes Matter

Use appropriate pipe sizes, especially when the pipework falls significantly below the unit. Consider adding an air admittance valve or increasing pipe size to ‘break’ syphon.

6. Prioritize Accessibility

Ensure easy access and removal of the unit for maintenance. If boxed in, the boxing should be easily removable, and any extension between the WC pan spigot and wall should not exceed 200mm.

7. Separate Discharge Pipes

Run each Saniflo discharge pipe separately to the soil pipe. If combining wastes, it should be into a larger pipe on a gravity fall.

8. Secure the Unit Properly

Properly secure the Saniflo unit, especially when dealing with closed couple WC suites. Consider battening the cistern off the wall to make room for the Saniflo if needed.

9. Positioning Matters

Place the Saniflo behind the toilet, not beneath it, for optimal functionality.

10. Ensure Correct Connection

Electrical connection should be via an unswitched fixed wiring connector with a 5 amp fuse for Domestic range macerators. Check the individual instruction manual for Professional range variations.

 

By following these 10 golden rules, you guarantee correct Saniflo installation, ensuring it efficiently serves your home or commercial space. For more detailed instructions, refer to the manufacturer’s guidelines or consult a qualified plumber specialising in Saniflo systems.

F.A.Q.

Frequently Asked Questions

Can I carry out a saniflo installation myself, or should I hire a professional plumber?

While DIY saniflo installation is possible, we strongly recommend hiring a professional plumber to ensure a seamless setup and optimal performance.

What types of pipework are suitable for Saniflo units?

When carrying out a saniflo installation, opt for copper or rigid solvent weld plastic for discharge pipework. Avoid ‘pushfit’ and maintain a 1% fall on horizontal runs for optimal functioning.

How can I optimise the performance of my Saniflo unit?

Optimize performance by placing vertical lifts close to the run’s start, using smooth, long-radius bends, and ensuring correct pipe sizes and secure positioning.

Is it necessary to hire a plumber for routine maintenance, or can I do it myself?

Routine maintenance is crucial for optimal performance. See our descaling guide

What precautions should I take during winter to prevent Saniflo issues?

Winterise your Saniflo by insulating pipes, maintaining a steady temperature, and clearing drains for uninterrupted flow. Follow our guidelines to prevent freezing and potential damage.

Can I use Saniflo units in commercial spaces, and are there specific installation considerations?

Yes, Saniflo units are suitable for commercial spaces. Installation considerations include proper accessibility, separate discharge pipes, and secure positioning for optimal functionality.
