Actual rough in valve flow rate?

If this valve was installed but didn't have a spout installed, what would the maximum GPM flow rate be? I understand that the intended use is with a wall mount lavatory faucet trim and that trim would only be 1.2 GPM max flow. I'm just curious about the actual flow without restriction.
Asked by: Wes
Dear Wes, Thank you for your inquiry! The R3500-WL is a wall mounted rough in valve for a lavatory faucet. The restriction is in the trims that are to be used with this rough in which is 1.2 GPM (gallons per minute at 60 PSI). The valve doesn't have a separate flow rate. Best regards, Tanya

It seems to be that the hot water is limited, how do I turn the hot water limit up?

Asked by: JayKal
JayKal, Thank you for your question. With this model, the temperature is balanced manually. When only the hot handle is open, the temperature will be the same as what is provided by the hot water supply. We recommend that the temperature of your water heater be set no higher than 120 degrees. Best regards, Jon

delta is using this valve as a tub fill, will tub spouts and roman tub handles fit this valve and what is the gallons per minute?

Asked by: jodie
Hello there, Jodie! Thank you for your question. The R3500-WL is a wall mounted rough in valve for a lavatory faucet. The restriction is in the aerator of the trim that would be used with this rough in which is 1.2 GPM (gallons per minute at 60 PSI) flow rate. This would not suitable to fill a bath tub. Unfortunately, we do not make any wall mount Roman/Whirlpool/Garden tub faucets or valves. Best regards, Tanya

You indicate above this valve will work with tub filler T5799-SSWL. However, it's listed as a "sink valve" on Home Depot's website. What is the GPM rate? Plumber recommended between 5-7 GPM for a tub filler. Is there a better valve for the tub filler?

Asked by: ShopperShopper
Hi, ShopperShopper! Thank you for your question. The Delta T5799-SSWL has a flow rate of approximately 8 GPM at 60 PSI. Best Regards, Rosanna

Can the valve be installed upside down if you reverse the stems?

Can the valve be installed upside down if you reverse the stems?
Asked by: Rick
Hi, Rick! Thank you for your question. We recommend to install this right side up. If absolutely needed, you can install this upside down. The stems are not reversible. You will have the hot and cold water lines opposite. Best Regards, Rosanna

Rough in suggestion

I’m going to use the trinsic RP77350 wall mount tub filler less diverted and the trinsic H659BL handles to do a wall mount. Do you have a suggestion for which rough in I can use?
Asked by: isackem
isackem, Thank you for your questions. Unfortunately, we do not have a rough-in valve for these parts. The H659BL handles are designed for deck-mount Roman Tub Faucets. The RP77350 can be used with an R10000 Rough-In Valve and any 13/14, 17, or 17T series trim kit.
