I have a bubbler system not working so well in a raised planter. There are buried wires running from a timer and it would be a lot to dig up, so I just want to convert to a drip system. I found a Toro converter and screwed it onto a riser then attached the 1/2 inch hose. From that I connected all the 1/4 inch hoses and drip emitters. Unfortunately when I turned the system on, some of the emitters exploded and there was water shooting everywhere, even though they were DIG pressure regulating emitters. I think the pressure is too high. How can I fix this? Thanks!
