I m using hitachi pump, very noisy and also the pressure drops a lot when another person turn on the tap. Gonna move in to my new house soon and my contractor recommended Grundfos. Will grundfos have the same problem? any member can share their experience?

just bought my Grundfos water pump from zheilwane, good price and good service with explanation in details of the water pump.

might be drop by your shop for more stuffs, zheilwane, can i get more discount?
