I have been bleeding this valve daily as an automatic bleed valve would do and heating and hot water is working great. Purpose was to prove if an automatic bleed valve would work. Does anyone have any comments regarding the fitting of such an item?

OK getting a bit out of my depth!! Will book plumber tomorrow to take a look for me. Are there any quick checks I can do to eliminate the abvious? Somebody mentioned putting the end of the vent stack (Manual bleed valve) into a beaker and then turning pump on to see if it sucks any...

Here goes and apologies if this makes no sense! Tank in loft of 3rd floor, pump in airing cupboard on 3rd floor and boiler down stairs. 2 large pipes and 1 small pipe going from boiler to airing cupboard. Description of airing cupboard area. Small dia pipe from airing cupboard to loft...

I will have a look today although I will struggle to draw a full diagram as I am a plumbing novice. Could you answer me one quick question - would it do any harm to change the manual bleed valve to an automatic bleed valve so that any air sucked in on pump start is is blown back again...

Sorry I did not understand the question as I a novice. Can you give me a bit more information on what the main vent pipe and the F&E tank and connection are and I will find out hwere they are for you?

sorry but I do not know how to look into your profile. What in particular do you think sounds wrong?

Would really appreciate some advice on the above problems if possible!

Thanks for response. Boiler is downstairs. Hotwater tank is in airing cupboard on level 3. Pump is just above floor level in airing cupboard with h/w pipe feeding into tank through a 3 port valve. Other port goes off to heating. Vent pipe is located after 3 port valve next to water tank...

My hot water vent pipe rises 200mm above the HW in pipe going into the 3 port valve. Is this long enough? I have recently installed a new Grundfos 15-60 pump (for 8 rads) however I think it is sucking in air on start up due to pump inertia and I suspect it is coming down the manual bleed...

Can anyone advfise me on the above as I am really desperate to get my heating going this week if possible. Any advice would be greatly appreciated!

ChrisR thanks for your response. Just a couple of questions beofre I do this test. aplogies if they obvious but I am a novice! The vent stack pipe on my system is not curved downwards? It is straight up i.e. vertical. How would I get this into the tumbler of water? Also you say this is...

I have 7 rads over 3 floors. I installed the pump as it was the same speed as the one I took off. I think it is pump inertia sucking air in on start up as it works great once I bleed it. the air builds when I stop and start the pump. I have the pump on the lowest speed and the hot water...

I am not sure. I think it is becasue the new pump is not as worn as the old one which I took off? It must be sucking air in from somewhere? Once bled the heating and hot water work perfectly? Would the auto bleed valve be better than an air seperator?

I am a plumbing novice! Can anyone advise me about an automatic bleed valve? I have a manual bleed valve on top of the vent pipe next to my hot water tank and above my Grundfos 15-60 pump that I recenlty installed. I am having to bleed the pump and bleed valve daily due to a build up of...

did you ever get this sorted as I have a similar problem? my pump requires bleeding daily in order to work properly? it is a new pump? ______________________________ lynda, moderator dannyo, its unlikely you will get a reply from either since they both stopped posting in 2004 please read...

Help - air in pump again after running on lowest speed for a few days? Once air is bled from pump and vent pipe above the pump the system works great? Is there anything I can do to the system to stop the air getting getting into the pump?

Wow. turned speed to mimnimum last night and system worked great with litttle or noise from pump and piping hot central heating! Worked this morning fine also! I will let you know if it starts to happen again but I am pretty sure it has solved it! Thanks for everyones help!

it is still doing if anyone has any suggestions I would be grateful?

I am pretty sure its the right way round. It has an arrow on the pump which is the same way round as on the old one ie pointing otwards the 3 port valve. I did drain the system down when I changed the pump. How many times would the pump normally need bleeding on a typical system drain...

I installed a new grundfos grundfos 15-60 water pump a week ago. Trouble is my heating does not work until I bleed it? I have bled it two or three times a day for the alst week. It works great after I bleed it but next day air seems to back in system. My boiler is down stairs and pump...
