Unfortunately some cheap imported tapware is very basic with a high lead content. When you purchase a tap feel the weight of it compared to domestic taps. If it feels heavy it may have a very high lead content which can leach into the water supply when the tap is off. This is not good for your family’s health and the tap may not last the distance. If the tap is not stamped with the manufacturers name then make sure you buy parts from the supplier for future maintenance. Note the name of manufacturer and the reseller so that the plumber can source parts when repairing the tap in the future.
