Landlord is using water I pay for in California.

[Raymond Navarro]

We were required to switch all utilities under our name prior to moving in or even signing the lease. No where on the lease does it state the landlord will have access to the water. The first time we noticed them watering the other side, we approached them and reminded them that we are paying the water bill (there's only one meter). We proceeded to let them know that we had to change utilities under our name in order to sign the lease and the cost was $150. At first they did seem concerned and assured us they will change the water utility under their name, then that they would install a second meter, but none has happened, and now they have arranged something with the property management company. The property management company made a decision and said that's the way it is going to be and my concerns  

I have reached out for legal counsel, but wanted to tap into the wealth of experience here. I just want to be treated fairly, but the landlord and property management company is pushing an arrangement on us without us being in agreement.

Any advice or shared experiences would be greatly appreciated, thanks!
