Installation/replacement of siphon trap in wash basin

Fitting or replacing a siphon trap — 600 CZK. The price covers removing the old unit, fitting the new one, connecting it to the waste pipe and testing under load rather than by running water for a few seconds. It is replaced when the joint still drips after a new seal, when the plastic thread has cracked, or when drain smell comes back into the flat — almost always a dried-out or leaking trap. Shallow shower trays need a flat model, so state the type when you order.
