Plumber Needed to Install Second Washer Dryer

I’m looking for a qualified plumber to install a second washer dryer in my laundry area. The second machine will be placed on a sturdy shelf directly above the existing washing machine, with a partition/shelf structure in place between the two machines (this is not a stacking kit). There is only one existing waste outlet, currently used by the lower washing machine. The job will require adapting the existing drain (e.g. fitting a Y-connector or twin appliance trap) so that both machines can safely share the same waste pipe. The installation should: • Use the existing water supply • Adapt the existing waste outlet for dual use • Ensure correct drainage height, no backflow, and no leaks • Be safe, secure, and compliant with plumbing standards No major plumbing works are expected, but professional assessment and correct installation are essential.
