Kohler diverter reducing water pressure by 4-5 times :(?

Hi,





I recently bought bath and shower faucet from Kohler.


(http://www.kohler.co.in/onlinecatalog/detail.jsp?item=567724%26amp;prod_num=K-675)





After installing it, I found out that its reducing the water pressure by at least 4-5 times because which I am not getting any pressure in shower.





E.g, If I measure the water pressure in terms of how far it shoots out when its at floor bottom and coming directly from tank, it goes upto 6-8 feet. Then the water travels upwards, passes through diverter and reaches the shower point and it gets reduced to 2 feet if measured in same manner. This means I do not get any pressure in shower





Is this normal behaviour of a diverter or something is wrong?





Thanks|||ok 1st of all that not pressure loss its VOLUME loss...u can only test pressure with a proper guage so u r losing volume....that amount of water u get......that sounds like ur shower riser...the pipe that goes from ur valve to the shower head is crimped somewhere.....if not then turn the water off to ur home and take the stem out of the valve then have someone turn the water back on with u in there then count to five and have them turn it back off......if there is any trash past the stem u cant see it will get blown out.....also what u can try is...with the water still off and the valve stem still out.....take the shower head off the blow thru that pipe making it flow backwards from original.....that way is something IS in the line after the stem it should get blown out too.....its got to be one of the two.....see it too many times....good luckl|||I have a similar Kohler bath and shower with no problems what so ever. Kohler has a lifetime guarantee, and I've found them to be very helpful on other problems. It's possible that you don't have the stem of the handle turned correctly-it has to be in one position so the the temperature regulator works right to keep you from getting burned when somebody turns the cold water on.|||a diverter is just that a diverter,is your shower head the trouble?|||It does not sound normal but call 1-800-4KOHLER (456-4537) and their technical people can tell you for sure!
