First job is to zero check of Tx.
If it will show zero meanns, Tx is ok on its 0 value.
Now u hav to close both isolatoin valve of Tx manifold.
Now open the drain plug of Transmitter.Tx show 0 value.
Next to open drain valave of both H.P AND L.P.(LIR).
The total water will drain out from impulse pipe.
If still u r not getting any flow of water in drain line it means ur lines are severely choked.
After jamming cleared again u hav to charged Tx by some step by step procedure.If condensing pot is there then u v to carefully charge the line.
