DERBY. Dear Mr. Robotham, Re the pumps which I brought back yesterday. I have tested these myself this morning with the following results:- RB.{R. Bowen}759/GM1. Date of manufacture 1/5/36. I could find nothing whatever the matter with this instrument. It pumps at the rate of 31 gallons per hour, but I will leave it on test for 48 hours to await developments. RB.{R. Bowen}1368/GM1. Date of manufacture 17.7.36. Leaky diaphragm. RB.{R. Bowen}1356/GM1. Date of manufacture 14.7.36. This pump would not prime at all. On examination I found that two valves were in one side and none in the other. On putting the valves in their proper place, the pump is apparently O.K. I do not think we can be blamed for this. RB.{R. Bowen}1007/GM1. Date of manufacture 8.6.36. Would not prime on left hand side. On removing the valves and refitting, primed O.K. but the left hand side had a warped valve in it, leaking back more than normal.
