I have oil-fired central heating system. Salamander ESP100 pump was installed (by a pro) about 2 years ago to feed a mains-fed shower. The pump is located on the same floor level as the shower. Over recent months its been taking longer and longer for the pump to kick in when shower is turned on. We have to repeatedly turn shower on off, and hold shower head at lowest possible height before pump kicks in.
Any idea what is wrong?
Also, the darn thing is extremely noise; I have placed it on top a price of carpet on top of chipboard flooring boards (the problem described above started long before I did this so). Any other suggestions to reduce the noise?
