Good. Don’t waste your money on a 0 to 15 psi gauge like I did. It was still impossible to try a get a steady reading of 3 psi. It was a Webcom decent gauge as well.
Good to know. I tried to order one but gave up as they didn't have 6mm connectors in stock. Instead I did a flow measurement, so my pump seems OK. Bentley says it should be 400 ml/min minimum. I got 1250. I realise flow rate and pressure aren't the same, but I'm reasonable confident that my pump is delivering.
