一連上新花灑,開唔到熱水爐..

是新花灑出水量太小,這種花灑只適合貯水式電熱水爐用,你要買個出水量較大的花灑,因為不是新花灑品質有問題,而又用過,所以應該退唔到貨,都你送俾人la.

是花灑出水的壓力問題, 最簡單是換個一個, 市面有些店舖賣的是可以適合不同水壓的花灑, 退貨我想就唔得啦.
以上資料希望可以幫到你.

I had the same experience before. There may be a small plastic ring inside the water tube. See if you can remove it so that there will be more water running through the tube. Hopefully, that will keep your water heater on. That worked for me.
