On an OSO?!?internal bubble
1. I would have felt the T&P discharge pipe to see if it was hot, if cylinder is hot then any discharge from it will make the pipework hot.
2. If it is cold then assume the relief is discharging.
3. Checked the expansion vessel & drained down & recharged the vessel / bubble.
4. Re-filled the cylinder set it so heat & check for further discharge if none then monitor, if there is then loosen the nut on the discharge side of each to confirm if it is the relief or the T&P replace as required.
Series 20 & I think 16 are bubbles Dave.On an OSO?!?
Thanks Chris. Gosh never knew that.Series 20 & I think 16 are bubbles Dave.
Come on Ash there must be something to accommodate expansion, either it is a bubble top or it has a vessel/s ?
If it hasn't got a vessel did you recharge the bubble, it could be that the expansion relief was discharging because the expansion was not being accommodated.
In which case it just needed a service.
If I isolated the inlet but it's the t and p that is faulty would this not continue to run after I have isolated?
Thats because you never asked BBA.Thanks Chris. Gosh never knew that.
