Review on KOLERFLO Pressure Booster Automatic H15GR 15 by Adrian Smart

Revainrating 4 out of 5

Has no NPT connections. Requires threaded adapter

I installed a shower pump last month and got about 20psi. However, I noticed that the motor gets very hot. Using a laser thermometer, I read 155 degrees Fahrenheit on the case. I fear he will have a very short life. The connectors are G thread (BSP thread form stands for British Standard Pipe) and are widely used in Australia and Commonwealth countries. It is based on trade size, not actual diameter, which can cause confusion when measuring fittings. There are two types of BSP streams; - Parallel (BSPP) - aka G or Rp - Tapered (BSPT) - aka R or Rc. Both threads have the same pitch, angle (55 degrees) and shape (rounded top and bottom). The pump requires NPT to G adapters.
