I don’t know what that means?

Here is a picture of the pump

Its a pump to just pump the condensate out of the boiler not to take the discharge from the cylinder

If the safety valves on the cylinder were activated the pump would not be able to cope and it would flood.

No check valve on the secondary either

Condense pump & discharge pipe probably melt as not rated for high temperature water.

What sort of pump should it have? I can’t have my basement room filled with boiling hot water.

Who suggested the install of this to be suitable for a basement without drainage?

The plumber/engineer suggested it. We had a combi that we wanted replacing and he said it was the best option given the number of bathrooms

The last one I did in a basement had a galvanised tank with a submersible pump rated for 95 degree water.

Thanks for the advice. The other pipe going into the pump is the combined combined prv and condensate pipe from the viessmann system boiler is this correct?
