megaflow and shower trap?

[finks]

hi all
any sugs for the best trap to cope with megaflow powered shower,i have tried several to no avail,are the venturi style traps any good or would a shallow bath trap give better performance?
ps waste pipework is all standard 1.5"
many thanks

Never known any problems with any bath/shower trap on a megaflo system as long as it is fitted correctly and clean

Have you measured the flowrate? More than 10 litres/min is excessive in my opinion. Its not a rose showerhead is it - they can produce massive flowrates if the restrictors are not fitted.

waste pipe has good drop ,and seems all ok but standard traps are leaving tray full of water while shower pressure on high for more than 2 minutes?

i will check flow rate and yes shower is fitted with a rose head,not sure about restrictors ,i take it by checking the flow rate i will know if fitted with restrictor.
thanks
