FAQ — frequently asked questions
Where should the 19 L sink decantation tank be installed?
The Mestra 19 L sink decantation tank is installed directly under the sink, between the sink outlet and the Ø 40 mm drain line. Check the available height (around 450 mm) and access for maintenance. Position inlet and outlet according to the flow direction to optimise decantation and always check tightness after installation.
When should the collection bag be replaced?
Replacement depends on the volume of plaster and solids processed. Regularly check the level of sludge in the tank. When the bag is nearly full, close the outlet, remove the supernatant water and dispose of the bag in compliance with local regulations. Regular replacement maintains efficiency and reduces odours.
Is a flocculant recommended with this sink decantation tank?
Yes, a flocculant significantly improves the decantation of fine particles. Tablets such as GIPEX Tabs agglomerate fine particles into heavier flocs that settle faster in the collection bag. The drainage system is better protected and clogs less quickly. Always follow the manufacturer’s dosage and safety instructions.
What maintenance precautions should be followed?
Shut off the flow before any intervention on the tank. Wear appropriate PPE (gloves, safety glasses). Close the bag outlet before removing it and let it drain to minimise spills. Clean the tank body and fittings if heavy deposits are visible, then check tightness after reassembly. Dispose of all waste according to current regulations.
