I have a 5,500 gallon cistern that gravity feeds my house and shop / garage; they are fed with there own 2†polyethylene pipe. The water level of the cistern should only fluctuate 2 to 3 feet. The water in the cistern feeds the fire sprinklers and potable water. The house is still under construction and the shop has been in use for a few months.
Last week my wife's car got bath from one of the sprinklers and also brought out the fire department. The sprinkler company thinks it was from water knock or a presser fluctuations in the system. We think the car wash started as my wife cut off the shower and the toilet finished filling. We have tried a few times to recreate it but no luck so far.
There is about 115' of elevation from the cistern to the shop. The pipe run was 380'. The static water presser is 51psi. There is a 32 gallon presser tank that is precharged to 48psi. There are no check valves.
I talked to one well driller and had no idea. Talked to a plumber and he was talking about added 2 more tanks and a check valve; but once we drew it on paper he had no idea. I started thinking it could be water osolation between the presser tank and the cistern causing a psi spike. The cheapo psi gauge dose not show much but have a better unit on order.
I'm open to suggestions, ideas, and questions.
