Hi chaps.
Will be brutally honest here so I can take a bit of stick if I need to.
I have DIY installed a Salamander CT60BU for a mixer shower and hot basin tap, the pressure is fine but the unit is really loud and whiny.
I opted for a negative head pump on Salamanders advice as I have installed a mixer tap on a gravity fed system (please don't hate) and obviously I wasn't sure if the flow rate would activate a positive head pump so the chap on the phone to opt for a negative head just be on the safe side.
Are negative head pump generally louder? As it doesn't sound like the pump will last the test of time. I can only imagine the noise is been generated by air entering the pump but I'm not sure how.
The pump is fed from a dedicated 15mm pipe from the cold water storage tank in the loft (I've checked that this isn't been drained by the pump in operation). The hot side is fed directly from an Essex flange on the side of hot water tank (in the bathroom) and down straight into the top of the pump.
I've isolated the electric for the pump and ran the hot and cold independently and the flow is good, quiet and smooth. I've also disconnected the outlets from the pump and ran water through it, again no issues.
Heard bad things about Salamanders warranty honour so don't want issues down the line.
Thanks in advance for any opinions.
