Leaky sprinkler problem

profenx

Hello ppl

I ran into a sprinkler that has been giving me trouble so I haven't been using it. It is under a slab with an irrigation cover. The sprinkler ends with a 12 outlet drip system (only using 4 outlets). The water drips out fine from the 4 used.

The sprinkler is leaking when on and fills the irrigation cover. Also worried about water running under the slab and to the house. How do i get it to stop leaking? Can it be replaced (but the cover is so small it would make replacing any part of the unit difficult so this is a last resort)?


The screw on the left seems to open and shut water from where the leak is. I can't remove the screw. I was thinking of replacing it with a metal one? It's plastic and almost started to break when I attempted to close it really tight. When closed water still comes out of the thing on the right, but slower.

It was already installed when i moved into the house. I've read about sprinklers but they all look different from this one. What type is it?

Appreciate any help i can get!

Thanks!

anyone?

How about what kind of sprinkler to replace this with? Do i need to replace the whole thing or just the part that is leaky when on?

The screw i've been turning turns out to be a flow control. So lowering the flow obviously lowers the leaking area, but still i get enough water dripping from the outlets.

Would appreciate any info on this.

Thanks!

I believe the device on the right, with the "TORO" label on it, is you "back-flow prevention device" or BPD. This is to prevent any residual water in the sprinkler system from back-feeding into your water supply, well or municipal. It appears that directly under this BPD is a union, and I'm thinking (trying to remember) that just to the left of the BPD is a black plastic union. Taking these two unions loose will allow the BPD to be removed. These BPD's are notorious for getting a very small piece of grit, calcium, whatever, in them and creating a leak. Some models can be taken apart for cleaning. And yes, the screw is a "flow control adjustment", controlling the flow/amount (not pressure) of water emitted from the drip system.

finally a reply! thanks!

Ok been looking for a BPD but they are all ... nearly double the size. Maybe i'll hit a small garden center or something. This thing is pretty small compared to my regular sprinklers in the front ... so i had no clue what it was. I'm gonna see if i can rip it apart to fix ... but the cap doesn't seem to come off. i guess it's not a serviceable part.

Thanks!
