Vaillant Ecotec pro Low working gas pressure

[Victor555]

Nope. I fit one when installing the boiler. As I once had 14.5 at the valve. Put a test point in before the boiler and had 19 at the boiler.

Thanks Very interesting ...

On a side note. When I requested to have the condensate trap cleaned, he put it back without filling with water. When I asked why? As Service manual says to, his reply was no need for this type of boiler, when boiler runs it will fill by it self.

Is he right?

No. The condensate trap should be filled prior to running the Boiler. If the trap is dry, products of combustion will exit the condensate pipe termination point until the trap has filled.

If all that you say is true, I think you should voice polite concern in writing (email) to the service manager.

We’re you watching, reading the book and offering an opinion during the service?

Doubt it. Bet it was all after thoughts.

Was watching, but not offering an opinion.

This thread is full of contradictions

Valliants are known to loose pressure through the gas valve ask your GSI to install a test point before the gas valve and retest , you should have 21mbar +/- 2mbar at the meter and 20 mbar +/- 2mbar so no lower than 18mbar at this test point on full load . Kop

So what I said😛😛😛

Just busting you b***s mate

 

[king of pipes]

Sorry H didn't see your post mate but great minds bud! I had the same issue on a council contract years back so now fit a test point before the gas valve saves alot of grief . Kop

When he did the annual service did the engineer also open up the burner and brushed through? Has he checked the exp. vessel, flue integrity, has done all the **** ? Seems like he either was lazy and rushed the service or he has not got a clue. As @Last Plumber has mentioned if that all is true you should perhaps write an email.

No, burner was not opened and brushed. exp, vessel was topped up.
**** was done with a print out.
does my gas pipe have a gas test point valve? have attached a photos.

There is no test point installed as far as I can see. How did he re pressurise the exp.vessel ? Did he drain the boiler ? I do not mean the flue gas analysis I mean **** which are certain things to examine, gas rate, integrity of the flue, supply of combustion air,safety controls, etc...

I am not sure, but this was ticked on the service check list.

Was it Vaillant that Serviced it?

ID

 

[ShaunCorbs]

P1 is the gas valve he hasn’t added his restrictions

14 plus 3.5 of vaillants are 2.5mbar 17.5 working at the gas valve

Low working pressure is not id unless it effects combustion

 

[Last Plumber]

P1 is the Boiler running at Max and he has tested the pressure at the valve. Shaun is right with the drop on a Vaillant in that the pressure will be higher at the appliance inlet than at the valve test nipple. Your Boiler will be three this year and I can't remember when the manual was altered but if you have the one left by the installer and it says 13 mb min, then ask them to come back.

The boiler also has not been cleaned as it should be done annually. He did not open the burner and cleaned and checked the electrodes. I would also say that the gas rate seems dodgy to me meaning I don’t believe he has ever done it. However, I would call them back

 

[Victor555]

Yes, after a long phone call today, another engineer has been booked for tomorrow.

I will be surprised if they got it wrong then mate. Don’t be annoyed if they say exactly the same thing.

It’s not required every year

 

[Harvest Fields]

You’re supposed to remove and check on annual inspection mate. It is the seal that is not needed every year. I hate to say it but on this occasion I believe he is correct.

 

[sammathias]

4.5mb drop through them gas valves lads. Well that's what vaillant tech once told me

New seal needed every time the burner is removed?
