Safety checks?

[macka09]

Hi all.

What safety devices are regularly checked for operation on a combi boiler?

 

[SimonG]

On an oil combi, away from the burner and oil supply, I always check expansion vessel charge and pressure relief valve activation. Even if it wont reseat and I have to fit a new one.

Do you test the new one?

 

[SimonG]

Indeed.

 

[macka09]

Manually or raising the pressure?

 

[SimonG]

Manually.

 

[AWheating]

are you talking gas related for a landlords cert? flame supervision?

 

[macka09]

Preferably gas yes.

Basically without discussing gas on open forum you would

Do checks in accordance with MI, TB12 and reg 26.9.

How you would do them im not saying.

 

[firemant]

Manually.

With respect, how is that "testing"?. A proper test, if you are going to do it, IMO, is to make sure the valve opens at the required pressure. (Although I dont do oil, just gas). Personally, I don't - there is way too much chance of the valve not seating and causing a repair, or worse, a call back. I don't know about oil boiler PRV's but gas ones are generally make/model specific, reasonably expensive, and can be a real pain to change.

I never set off a prv. If it aint dribbling - its working as far as im concerned

What amazes me in this industry is that there's set regulations that we have to adhere to. As mentioned 26/9. Yet out of the very few replies to this question, there's already a debate about whether a specific test should be carried and how it should be done. Are the regs put in place as guidance and should we determine how to use them ? We all do things very differently.

Manual is better than ignoring because you cant be ar$ed to fix it.

Its just making sure it lifts and has not been manufactured incorrectly or seized in place.

Oil ones are about £6 and a piece of p to change.

Oh, with respect.

Don't you always get it was fine before you touched it.
