Bateman leaking nozzles

[LH10]

Recently purchased a 2008 RB17 Bateman low hours running Topcon x30 10 section shutoff and autosteer. Have noticed when filling up ie self fill and Chem inductor some sections are dripping, they are not individual nozzles they seem to be sections of 4 nozzles or so. Have tried filling with Ramsey Valve at different pressures doesn’t seem to make a difference. Any help appreciated thanks

Are the non drip valves non working properly ? Perhaps there is a build up of chem in them stopping them sealing properly

You need to check dcv rubbers and make sure that the chem savers haven’t punched a hole through them!
Next step after that strip, clean and lube chemsavers with Vaseline!

It will be the dcv rubbers like Jetemp says easy fix

As above, expect it's the chem saver rubber disc worn through, unscrew the round plastic tube with air pipe fitting(can leave pipe attached) and inside is the DCV rubber. Phone up Bateman and they will send a bag full in post. It may pay when you have a quiet time to replace the lot and start afresh. I do mine every year before spring work.
I can honesty say that the actual chem savers don t tend to have problems. There is a kit with 3 or 4 different "o" rings which I have ( to re build)but I find that if they give grief they carry on so I have a couple spare chem savers in my tool box and just change the whole thing. Would of maybe changed 2 in 5 years

Was that bought from @Feldspar ?

Sprayer was purchased from TM SILLS Essex.

That’s him!

@jackward6170, Paul Cowlan at Challis Reed is very good, so worth giving him a ring if the above advice doesn't sort it. As per @Oscar's advice, normally swapping the rubber sorts out any individual nozzles dripping nozzles. Didn't have a problem with whole sections doing it though. Let me know if you don't find a solution.

Would the chemsavers stop the nozzles spraying?only I keep getting the odd nozzle or 2 on a section stopping spraying or failing to start spraying when I set off then can come on as I progress down field!!
Have changed all the diaphragms .
It's a bit frustrating!!!

Either you're trying to spray at too low a pressure, or you need to spend some time with your chemsavers and a tub of vaseline

Had my MOT today on rb25 so these are fresh in my mind! Dripping individual nozzles tend to be diaphragm rubber disc in the chemsaver, a not-working nozzle tends to be a chemsaver seized so get the lube out; a chemsaver leaking liquid out of the back of it usually means a new chemsaver. 24 ish quid from Bateman. HOWEVER….op said it’s happening in whole sections so either there’s a lot gone and it’s coincidence or there’s something going on with the section control pipework I’d say. I’d have thought if a section was slack/had a leak a pressure test of both air and liquid would isolate it

is the boom recirculating system working properly?

Yeah nozzles don’t seem to be dripping and turn on and off sharp but just have these isolated intermittent ones that don’t come on for a while.usually spraying at 2 to 2.5 bar so shouldn’t be an issue there.
Perhaps I need to take 1 or 2 apart and freshen them up?see if that works
