Less than a year after replacing the seals and springs, my Delta shower control is leaking again. It may be that I installed the wrong springs, which resulted in the seals wearing out prematurely. According to the kit instructions, the spacing of the sockets inside the delta shower control determines the size of the springs to use for the seals. I did not pay attention to this feature and probably should have left the old springs in their sockets. So, based on the spacing between the sockets (mine is about 1/4"), what size springs should be used?

Can you furnish us with a model name or number? Back to you. Tom

I did not see a model number when working on the shower valve; however, from the Delta website, the parts diagram that most closely matches my valve is for the Classic Series, models 601, 602, 611, 612, 621, 622, 635, 636, 641 & 642. It is a single handle shower control valve. The Delta part number for the seals and springs is RP4993, which is what I installed, but it seems like a shorter spring would have been a better fit.
Thanks, Art

Is this your valve? Let me know, Ton

No.

Delta seats and springs are made to fit all Delta faucets. There's only one size. This link may help. How to Repair a Leaky Delta Shower Faucet @ jammer(six) Good luck, Tom

I misread your question; I thought you meant did I own the valve. Actually it's a neighbor's valve, which I was repairing. However, you were referring to the attached diagram, which I believe is the correct diagram for this valve. I replaced the seals and springs with part number RP4993, as shown on the diagram. The instructions with the kit indicated that if the sockets (or holes in which the springs are inserted) were very close to each other, replace the old springs with the kit springs, but if the sockets were approximately 1/4" apart, leave in the old springs and just replace the seals. In this valve the sockets were 1/4" apart. Since this was the second overhaul in about one year, I assumed that I should have left the original springs in the valve during the first overhaul. The implication is that the original springs were shorter than the new kit springs, which may place too much pressure on the seals and thus shorten their life. So getting back to my original question, is there another set of springs (shorter/weaker) which I should install?
