hello everyone. we are in the process of adding new pipes for water distribution. being new in our company, i noticed that gate valves are being installed "only" where tees are located. May I ask then, what is the proper spacing of gate valves. How do we install them?

thanks a lot! we've increased the pressure and already fixed the air release valve.

another thing, could you please give me an idea on how to determine the proper size of air release valve for a certain pipe size say 6" dia. PVC pipe for example.

hello everyone. we have tried putting an air release valve at the highest point of our distribution main. what happened was instead of air being released, air is being sucked by the pipe into the distribution main. can somebody explain this? we haven't put the ARV yet, only the ball valve at...

To quark, the depth of the well is 100 meters and the pump setting which is 48 meters I believe means the pump will be 48 meters below the ground. To BigInch, the water will be distributed to consumers and at the same time some will be stored in the reservoir. Then i have to compute...

good day to everyone! i've just received the Pumping Test Report of our newly drilled well and it's my first time to see such report and i'm just new in the field of water distribution. kindly help me select a submersible pump based from the report. Their recommendations are: Q (discharge) =...

thanks everyone! good thing i found this site. (i've included this site in my Favorites!)

good day to everyone! i'm a newbie in the field of water distribution working for a water district company. kindly help me decide whether a 2" diameter pvc pipe is enough for 100 service connections or a 3" pipe is needed. the pressure in that area is around 5 psi - 10 psi only. thanks. romer

i can't find this Water Treatment and Distribution Forum sir. where is it located?

thanks sir big inch. taking into consideration the pressure surge that might occur in case i'll connect the new 6" dia. (30 lps or probably more) into the 8" dia pipe (which carries 40 lps already). i think it's better not to connect the 6" into the 8" pipe which will result into a 70 lps flow...

we have an existing deepwell pump which has an 8" dia. transmission main. the new deepwell pump which is about a kilometer away from the existing one will be having a 6" dia. transmission main. the choices are; 1. either to loop them 1 kilometer away from the new pump or , 2. connect the 8"...

the 40 lps and 30 lps flow rates (8" dia. and 6" dia. respectively)are from the discharge side of two pumphouse. does that mean they'll slow down let's say 500 and 1000 meters respectively (again) from that point? thus slowing down also the velocity of the water up to the point of...

hello again... I was just hired last week for my current job here in our city water district. We already have an existing water pipelines here in our area but I want to have a better understanding about piping for water supply. Does anyone here have articles or web page that talks about piping...

Thanks for the inputs. Actually I already computed for the velocities of water on each pipe based on the given areas and flow rates on each situation, before and after connecting the new 6" diameter PVC pipe. I've used the continuity equation, Q=aV, for the computation of their velocities...

hello everyone, i need some help from our expert members. we have an existing 8" dia. PVC water line with a water flow of 40 liters per second which is being directed into two 6" dia. PVC pipes. now, we are planning to fix a new 6" dia. PVC pipe into the 8" dia. (its water flow is 30 liters per...
