[EU] Survival | Water Stuff not working

I can't use water stuff on my base.   Like, water barrels to valve pump works, but not outputing to sprinklers.

Fluid combiners stop the water flow.

Water pumps directly to sprinklers in the normal way can support 4 sprinklers, i just can use 1 sprinkler for water pump, does not output the rest.  

I left yesterday, and today the 4 sprinklers are working, all 4 outputing water, but just 1 is real, the other 3 are doing nothing  even dropping water.  

I can have an admin to see the problem 1st hand? or i can take a video
