so you have tried fitting differnt pump heads and they leak then? that is all i need to know.

Cheers for the reply, Everyone is shouting grundfos, but just because a pump is half the price does not make it any less effficient, does it?

Has anyone had any experience with these pumps and are they any good? Also would they fit in to the housing on a potterton performa 28? i would only need to change the pump head so am wondering if it would be a tight fit?

Should be but keep an eye on it as the seal could have gone. Also if you have a loop feed system you need to check the pressure as you have been losing water out of your system so you need to top it up should read between 1 to 2 on the meter. Hope this helps I am by no means a professional but...

When you say small pipe are you talking about the drain off, usually brass about inch long? If so it just needs tightening via the square nut on the end. If not give a little more information.

Make of boiler, type of system e.g. how many rads. would be helpful. then they will tell you to phone a professional.

Dearest does not always nessesarly mean the best. Its ok when you are spending someone elses money, but if you were doing it for yourself would you not shop around to see if you can get a better deal? Your Jai-Ling may serve you just as well as the Honda would, at the end of the day it is a...

Why pay twice the price for something that will do the same job :?: If you dont know the answer why post :shock:

Kev thanks for that :!: Although your posts are somewhat cripitic at times you never stick get a professional on the end of everything like some do. Awey the lads and all that marra :wink:

11 rads i would be looking at the top end then? think i will be having a play myself.

because it would be easier just to just replace the head if it is compaterable

how much would it it cost to have my system flushed professionally?

Will the pegler terrier fit in to the housing of a grundfos?

i have a pump that is clagged up with a greasy residue, i know this is due to running a system without being flushed. what i was wondering is can i free the pump by using a degreaser? if so any ideas what to use? i think the motor is still ok. the pump is a grudfos super 15/60.

does anyone know how to take the impeller off a grundfos pump, do you need a special tool? the reason i ask is that i have two pumps and the good pump, when i took the mounting off i caught the front face of the impeller and broke it off. so i was thinking that if i could change the impeller...

I am not sure if it is the same problem as I had. But try puttiing your hand on the pump to see if it is getting hot. Also another tip is to put a screw driver tip on the casing of the pump and your ear to the handle this is an easy way to check if the motor is still running but the pump is not...

I took the front of me pump off and gave it a spin, working like a dream now :D. I would not say i'm a compotent person to do this but I think I have saved myself a few bob for now. I'm sure it will come back and bite me on the bum at some stage. I can't seem to find any speed settings on my...
