A practical replacement guide for installers
Need to replace an old lifting station or macerator? Start by identifying the existing unit, then match the wastewater type and connected appliances to the right SOLOLIFT2 model. Next, check dimensions, inlet and outlet positions, pipe diameters and service access before removal to help avoid unnecessary changes on site.
With only five SOLOLIFT2 variants covering domestic blackwater and greywater applications, installers can choose faster and specify with more confidence. Flexible connectors supplied with connection parts and a 360° turnable discharge adaptor on selected models help simplify replacement work and reduce the risk of extra pipe adjustments.
Quick selection:
Which SOLOLIFT2 model do you need?
Use the application as your first filter. If the installation includes a toilet, choose a WC model. If it only handles greywater, choose C-3 or D-2 based on the sanitary setup fixture mix, temperature needs and available space.
When should you replace the old lifting station or macerator?
Replace the unit when performance, reliability or serviceability becomes a problem. Common signs include clogging, leakage, foul odours, higher noise levels or repeated service callouts.
For you, these issues can lead to more troubleshooting, more uncertainty and more time on site. A clear replacement process helps reduce that from the start.
Typical replacement situations
The old macerator or lifting station is unreliable or difficult to service.
The unit is blocked, leaking or causing persistent odour problems.
The customer wants a cleaner, more service-friendly replacement solution.
The installed product is discontinued or no longer easy to support.
A bathroom, basement or utility room renovation creates a replacement opportunity.
Step 1: Identify the old lifting station or macerator
Start by identifying the brand and model of the installed unit. Then use the SOLOLIFT2 Replacement Guide to find the most suitable upgrade and check whether the replacement is expected to fit directly, fit with minor adjustments or require extra installation work.
This helps you choose faster, prepare the right accessories and reduce surprises on site before the old unit is removed.
Step 2: Choose the right SOLOLIFT2 replacement model
Use the overview table above as the main model-selection guide, then verify the final choice against product documentation and local installation requirements.
For a quick visual refresher before choosing a model, review the Ecademy module What to look for when replacing a lifting station to reinforce key fit checks and SOLOLIFT2 selection guidance.
Step 3: Check dimensions, connections and fit
Before removal, confirm the replacement can fit the available space and connect to the existing inlet, outlet and discharge pipework.
Focus on the details that most often affect fit: dimensions, pipe routing, connection count and service access.
Step 4: Plan the installation before removal
Plan the job before disconnecting the old unit to protect fit, service access and installation flow.
Step 5: Install, test and commission
After installation, test the system before handover to confirm reliable operation, verify the setup and reduce the risk of a callback.
Run clean water through the connected fixtures and confirm automatic start and stop, leak-free connections and consistent discharge performance. Make sure the unit evacuates as expected and that there is no sign of backflow or poor drainage.
If performance is not as expected, check the power supply first, then review blockage risk, discharge resistance, non-return protection and whether the selected model matches the actual application.
