i live in a bungalow and have issues with the hot water in the front of the property, it seems that air is getting in.

I can’t get rid of the air by sucking it out but it happens again after about a week.

My local plumber has said I need automatic air valves and this should solve it.

Would you agree ?

If so where should I put them ?

ask the plumber that has seen the job , we havent so what makes you think we would know better than him/her ?
 
He advised on the phone and was a suggestion, he didn’t specify where which is why I’m asking.

If you can’t advise that’s fine and no need to reply

Does it come from a tank in the loft? is it filling properly? Is the cold alright? does it ever happen with other hot taps? why do you have to suck it out, do you mean it's an air lock and no water comes out the tap?
AAV might hide the problem but there shouldn't be a need.
 
It’s the hot and only off 1 feed which provides the kitchen and cloakroom,

Bathroom hit for bath and sink is fine

Cold is fine
 
??

Why so short, it’s just advice I’m after

Because it’s neither polite nor beneficial to “bite the hand that feeds you”!

As for your plumbing problem: it sounds as if the pipework is causing a syphon and an NRV would be more appropriate than an AAV.

Thanks for this, I see the NRV would be an option as this would stop air and water coming back up the system I guess

Would it hurt to put 1 in on each on the hot taps even if this wasn’t the issue ?

If so should I locate as close to the actual tap as possible or on the loft ?
 
Do you have a traditional gravity fed hot & cold water system ?

If so have any alterations been made to the system ?

Op you still need to answer this.
If so perhaps the cold feed to the cylinder is restricted and pulling in air via the vent pipe. If the tank is emptying then it would be that. Perhaps that is what dilalio means, but I'm not sure an nrv would assist if it's what I'm thinking
 
Gravity system

Hot water tank is in the bathroom, same level as it’s a bungalow

Cold water tank is fine and not emptying

Hot water in the bathroom is fine, it’s just the hot feed to the kitchen and cloak room, these are fed by the same pipe and T pieced in the loft
 
So if the t piece is higher than the water level in the header tank that would explain it.
If not I suspect air is being pulled down the vent pipe when some taps are in use and it is rising up to the tee afterwards.
You may be able to prove it by holding a glass of water over the mouth of the vent pipe and getting someone to operate the various taps in different combinations, see if the water disappears up the pipe.
