Found this for sale nearly new for £150 not too far from me. BARGAIN!! Anyone know what the jet code should be for 15ltrs a minute 2900 psi

2 x 15 025 nozzles in that, some would choose 25025 but I prefer the deeper clean of a 15 degree nozzle especially on block paving, however if you mainly clean flags etc then probable 25 degree would be quicker with less ringing?

I will be using it on flags and block paving. So I will need to change jets for each type of material?

that's up to you mate, see which works best for you, you will have better results on block paving with 15 degree nozzles as they are a more concentrated nozzle, but on flags the 25 degree will give a more even clean so you will be able to walk a little faster, I just stick to 15 degree because I can't be bothered changing and it won't make that much difference on time if you only do mainly domestic
