i was wondering. if the valve i have for my tub/shower could be a bad design. i have very low flow coming out for tube. in fact wife cant take a bath. it is that bad. shower is useable with a low flow shower head. if i get a gallon a minute i would be surprised for the tube. good flow out of all others ( sink, toilet,kitchen,outside hose). i have replace the valve cartridge twice.on the second time i flushed the line the water came out fast and hard. shot completely across the tub. not sure of the valve mfg. it is either BRADLEY-COLE or KOHLER the repair kit is from DANCO the only # i have are BR-1 and 80461.
any thoughts thanks Bob
