I'm so thankful I found you online! My local sprinkler installer told me I couldn't buy just the rubber cap for my sprinkler heads (my puppy chewed off 10 of them). I was looking at having to replace 10 heads at over $30 each PLUS a service call at $75/hour with an hour minimum (talk about being taken advantage of)! So I decided to do a little investigation on my own before committing to that and I found you! For under $25 (including the flat rate $9.95 shipping) I was able to repair ALL my heads! I will definitely come to you first for my sprinkler part needs!
