Setup, Compatibility & Care
Installation of the Marsh ENSIGN ULTRA must be performed by qualified drainage contractors who are familiar with local building regulations. The unit should be positioned in a location that allows for gravity-fed drainage where possible, using the 750mm riser to meet the depth of your existing pipework. To ensure the 25-year structural integrity remains intact, use only approved backfill materials as specified in the manual to prevent pressure damage to the tank. Regular maintenance, including annual desludging and inspection of the alarm system, is critical to ensuring the biological process remains efficient.
