New central heating pump - does this sound normal?

[cubegame]

Just changed the title of this post so it reflects another issue.

I have installed a new Pegler Terrier central heating pump to replace a broken Myson Unit Five.

After installing and bleeding I'm not really happy with the noise given out. I'm sure I've got rid of all the air but it still has a reasonable loud buzz to it. Much louder than the pump it replaced.

Initially when I installed I tried to run it on the lowest speed setting but it wouldn't start. In fact, it only starts on a higher setting or if I turn the shaft with a screw driver.

Is this normal? Once started it will keep running on a lower setting and warm all the rads but it won't restart once stopped.

This combined with the noise suggests to me it may be faulty?

Most pump motors are attached to the body by allen screws.The screws can be removed and the motor section can be rotated 90 or 180 degrees.What make of pump have you bought?

It's a Pegler Terrier from Screwfix. Doesn't look like it can be rotated because I wondered if that was the case. I'll take another look though.

Looking at the screwfix site both those pumps look as if they have 4 screws securing the motor and can be removed allowing rotation of the motor head.

Absolutely right! I feel quite stupid now, having lost the ability to recognise an allen bolt.

Now what does an allen key look like?



Cheers, all fixed.

Just bumping this one up for the new question.

Why do you think rotating the head will make any difference to the noise?

If you buy a cheap pump then dont expect it to be as good as the common Grunfoss or Wilo.

If it will not start on setting "1" then that implies its faulty ( too tight ) or it has already attracted dirt into the bearings.

The reality is that most pump replacements occur because the previous has failed due to dirt in the system. Obviously in this case the system should be cleaned before fitting a new pump.

The rotating the head bit was me being a bit thick last night. All sorted now. I just changed the title and first post so as to not have to start a new thread.

System was cleaned at the end of the summer so I guess I will be taking a trip back for a new pump.
