View Full Version : Delta Interchangability 1300 vs. 1700

In my condo, I have a Shower/Tub & a Shower, both with Single handle Mixet valves which control Temp & Volume. It was only after replacing my waterheater, that I became aware off the the Mixet crossover issue which I suspect was wasting energy by backflowing my hot water heater. So to resolve I first replaced the Shower/tub with a delta 1354. This model unfortunately does not offer volume control (apparently very few do), which I thought would be ok, but after washing my dog, I really need to control volume.

My question is this: Does anyone know if the Delta 1354 Rough-in (the brass contraption) is any different than the Delta 1700 Series Rough-in? In other words, are the valve Cartridges interchangable? If so, then I would be able to buy a Delta 1700 series, use rough-in for my Shower and Swap Valve Cartridges with my 1354 Shower/Tub. I hope this makes sence. :o

It can't be done. The pressure balancing function is performed differently in the two valves so the internal length of the two "cartridges" is different.

It was worth a shot. :o
