We installed this toilet in our powder room and in less than 6 months of use this toilet is malfunctioning. The wandnozzle that sprays the water is not functioning.. doesn’t extend to spray the water. The owners manual says if the unit buzzez three times in a row, it means faulty product but doesn’t give any instructions on troubleshooting the problem. They don’t have any phone number or address for customer service. Spend over 700 to see a broken toilet in less than 6 months of rare use is utterly disappointing. Also we beware they have only 30 days warranty with no info on where to claim.
