10-10-2009, 06:18 PM
hello- can anyone tell me if i can use the moen asceri shower and body spray jets with the posi-temp valve? If not, is there any part that will convert my valve so i can use it? Als, can I put asceri trim only on a roman tub with posi-temp valve? I cannot get to valve on tub, but am going to re-tile shower so I will have access to valve. Hubby will not solder, but i might be able to talk him into an easy connection. can anyone help? thx a bunch, sue (p.s.-please be kind and talk simple as i know nothing)

There are two types of antiscald technology available for showers: pressure balance and thermstatic (and some combine the two). Either should work. the consideration for any valve, doesn't matter the type, is to ensure you get one big enough to supply the desired load without restricting the flow, and not being able to provide the desired impact. This normally isn't a problem unless you have a lot of heads you need to supply. A 1/2" typical valve can flow about 5-6 gpm. If your shower heads need more, then you need a 3/4" valve, and 3/4" lines coming into it, so that may be the bigger problem.

When making changes in your plumbing, it is rare when at least some soldering is not required. Maybe it's time to call in a plumber...

Soldering isn't all that hard if you have any handy gene at all. Buy some fittings, a hunk of pipe and the required cutting, and soldering tools and practice a little. It's a handy skill to have, and doesn't take all that long to learn. While not quite the same thing, it takes about 10 hours to train a new person and certify them for electronic soldering to mil-spec abilities. Soldering pipe is a lot less exacting.

hi- can you explain a little simpler? I just want to know if the moen asceri trim can fit or can be made to fit on my existing posi-temp valve, both on roman tub and shower. (chateau trim is installed now). valve is about 8 years old. i am not doing any of the work, hubby will ne installing whatever i buy, i just know from MANY years of married experience that the job has to be simple for hubby or I will not be very popular with him for a while. does installing a jetted shower system fall in the easy category?thx in advance, sue

Post a picture of the existing valve you have. Once that is identified, you can then tell if any other trim will fit.

What you are proposing (adding shower heads and a new tub) is not, likely, a simple change. If your hubby doesn't feel comfortable, then it's time for a pro. Just changing the trim, if the new stuff will fit, probably is easy - it often is just unscrew the old, then install the new.

If you are considering having you hubby install the valve using "easy connections", then your first thing to do would be to call a plumber.
