Question: hi, do i need a saperate valve to controll on/off ? does this diverter inlcludes that function, or all 3 functions for 3 outputs ,thank you!
Document: So far we have changed 3 inside defective valves under warranty. If you need a diverter buy a different brand.
I like this. works well. Easy to install. Problem is I can operate any combination of 2 of the 3 shower heads I have but I cant operate all 3 at the same time. Why? No clue why they would make a diverter that can handle three outputs but not all at the same time.. ? ?
Worked great as a diverter valve for my shower, installed professionally, but will need the cartridge for this - comes WITH the TRIM KIT - hard to find the cartridge separately. Once everything came together, it worked great to provide both a handheld shower with the diversion over to a rainshower head designed and installed by me.
We own 2 of these. They rock. We use them with 2 shower heads, so that we have off, shower a, shower b or a+b on. We just don't have a need for shower jets.What is great is now we can keep the diverter by the shower entrance and the thermostatic valve all the way inside the shower - so we never get wet until things are nice and hot. The stainless trim kits are very nice.
Plus capping one outlet really only creates a 2 way diverter not a 3 way.
Was a perfect fit! Easy install, of course, since it's a rough-in version. I like that it was threaded already so I didn't need to sweat on copper fittings. I used CPVC threaded male adapters instead to CPVC pipe and it was easy 1-2-3. The part was even $50 less than my local plumbing supply store.
I ordered (I thought) a diverter valve. I got (turns out) a diverter valve housing. Neither Amazon nor Delta are clear about what on earth the actual valve is called or how to find it. Maddening. And, No I do not want to get the whole "trim" package. I will find it (but not at Home Depot, Lowes), but Amazon and Delta deserve a lousy rating for this (not deliberate but just incompetently misleading) marketing to DYI folx like me.
It worked perfectly with my 6 way trim and cartridge kit. I do recommend measuring or mocking up the finished wall thickness to make sure the mounting depth will give the desired finished look. The directions give a guide but might leave the handle too close or too far away from the plate, so get an idea before you mount the valve. One other thing to remember is that the valve should be flushed before  you put the cartridge in, to remove any debris from the lines and valve.
I like this line of products from Delta, the guts are the same for the entire line and once installed one should never need to get in the wall again. Price and delivery time was excellent.
Bought for matching diverter. Works great.
