Pumpover.

[75pete]

System gassing up due to chemicals added?

How about making a sketch of flow. return, pump, feed and vent pipes and reason under what circumstances water will pump over.

After the fault was fixed pump was set for speed 3 with nil pumpover. Reversed pump would not make a difference, neither would a closed iso pump valve.

Several posters have already given the correct answer

did me sketch my moneys on a blockage between vent and feed

Partial blockage

 

[DP]

22mm pipe between vent and feed was encrusted to a bore of about 8mm

After all that....what an anti-climax.
I found that problem on many occasions and always when the cold feed dipped before connecting into the flow. I always tee'd cold feed into the open-vent just before the connection to the flow and never experienced any blockage problems.

No pipework was replaced or altered.

.

Now we know the answer surely pipework must have been replaced or altered to fix...?

Unless he has xray lazer eyes like superman and burnt it away .

I would have expected Danny to have identified the blockage from outside the pipe on his first visit within two minutes !

[namsag]

WHY ?

 

[gas4you]

Because that's what Tony expects and is twice as long as he would have taken

 

[Agile]

I have the requisite tool with me when I go in, but I cannot assume that Danny carries his with him at all times and he might have to go out and look for one in his van hence the extra minute.

Seemingly Agile broke his record for continual sex on saturday night 1 hour and 2 minutes . Then he realised the clocks had gone forward.

Pipe was removed, blockage cleared and washed. Same stub of pipe refitted. So no pipework altered or replaced.

Tony, perhaps it should be said, I wrote this post to get the newbies to think through the malfunction. Clearly this exercise was not aimed at a genius like you but someone who is a recent start to get them thinking.

Anyway, how would you know what I carry in the van. If truth be told, I do have a magnet in the toolbox. I did not have to use it. Instead I reasoned why water was pumping over to remove the offending section.
