stuart turner showermate pump

aggi

Dear all, 
I just wanted to check if I have issue with my Stuart Turner pump. It is only 6 months old and I thought that 2 pipes should be warm and 2 cold. However at times 2 pipes are warm, one cold and one very hot, not being able to hold hot. pump is getting louder then and hot to touch as well. is this normal? I am worried that pipe is getting so hot it may cause fire? 

 thanks for all input

Does the pump need bleeding?

When you say needs bleeding do you mean like radiators? because of trapped air? I wouldn’t know what to look for and the manual doesn’t seem to mention anything about this. The ‘fault’ happened 2 so far that I have noticed. in between it works perfectly fine.

If one pipe is getting so hot that you can't hold it, have you checked the temperature setting on whatever method you are using to heat your hot water (boiler or immersion heater)?
If the temperature of the water being fed in was too high, this could possible lead to excessive heat transfer through the pump body leading to the cold water side of the pump getting warm (and would help explain why one of the cold water pipes feels warm).
If the pump was getting too hot due to the temperature of the water being fed in this might cause the impeller fan or a bearing to expand and explain the noises you are hearing.  

Next time it happens, try running some water from a hot tap and see how hot this actually is.

1. The maximum permissible input water temperature for these pumps is 65 degrees Celsius.  Any more any you will damage the pump and invalidate the guarantee. It may also damage the plastic connectors and cause a leak.  
2. The pumps must be installed in accordance with the manufacturer's instructions.  You can see a copy at https://www.stuart-turner.co.uk/contentfiles/Showermate-Standard-Single-and-Twin-IG.pdf

The pump was installed by plumber not a diy job. the tank is set to 50 C and the incoming hot water pipe was warm to touch (checked just incase the thermostat on tank blew) but nowhere near as hot as the questionable outgoing pipe. Will give them a call after work today 😊

They also make very good pumps
We have lived in our house for 12 Years. There was a Stuart Turner shower pump already there so I dont know how old it is
It has been used 2 or 3 times a day since and still performs perfectly
