impeller
An impeller or impellor is a rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid.
Hello everyone,

I was quite happy to unblock it myself using the service shaft above the motor and a long screwdriver, but it keeps happening roughly once every month.
When stuck, it makes a...

Hi all,
I'm pretty sure i'm correct here and not going mad but wanted to check before causing problems.

I have a customer who I am installing a new bathroom for. She has a vented system with a small (140 litre) HWC with an immersion heater and storage heaters for heating.

My question is if she changed her HWC to...
Hi
Our mixer shower has always run slowly with very low pressure (taps seem fine). We asked around and one electrician suggested a dual pump but also told us that this was really work for a plumber. So, we contacted a plumber, told him what the electrian had said and he came out to fit the...

My old Worcester combi has become noisey and seems to be labouring during this spell of cold weather. The CH pressure is normal, and has been good since I replaced the PRV in the summer.
It seems to have started since I turned the water temp setting up from about 1/2 to 3/4. The noise is a...

Hi
I'm sorry if this is going to be long-winded, but I had a water pump that served the hot and cold water to the whole of my house, but after just two and a half years it started to leak (hot side). I discovered that it was possible to fit a seal kit and the pump engineer came on Saturday...
