GIBSON
Frequently asked questions
Common questions about GIBSON from 3G Electric.
What is the Gibson Posi-Temp valve technology and how does it affect replacement part selection?
Gibson Posi-Temp is a pressure-balancing valve design used in bathtub and shower faucets. It maintains outlet water temperature within a specified range when supply pressures fluctuate. When selecting replacement trim or handles, the valve series must match. For example, trim kits for Posi-Temp T2903 series are not interchangeable with T3002 series without verifying the valve body. Always confirm the existing valve model number before ordering trim components.
What flow rates are available for Gibson showerheads and bathroom faucets?
Gibson fixed showerheads in the Posi-Temp series typically have a flow rate of 1.75 gpm. Bathroom faucets, including single-post and centerset models, have a flow rate of 1.2 gpm. These rates are consistent across the models listed and comply with common water-efficiency requirements. Flow rate is determined by the showerhead or faucet aerator, and replacement components should match the original rating to maintain performance.
What materials and finishes are used in Gibson trim kits and faucets?
Gibson trim kits often feature brass escutcheons with a chrome finish. Bathroom faucets are constructed of brass with a chrome finish. Showerheads may be metal or plastic depending on the specific model. Chrome is the standard finish for the products in this line. When ordering replacement parts, material and finish should match existing fixtures to ensure appearance and durability. For example, a chrome brass escutcheon is specified for Posi-Temp T2901 trim.
What is the difference between Gibson centerset and single-post bathroom faucets?
Gibson centerset faucets, such as model 6150, have a low arc spout and are designed for three-hole sink installations with a 4-inch centerset. They include a drain. Single-post faucets, such as model 6145, have a single handle post and include mounting hardware. Both are brass with chrome finish and 1.2 gpm flow rate. The choice depends on sink hole configuration and handle preference. Centerset models are common in standard residential bathrooms, while single-post models offer a streamlined look.
Can I use Gibson T2903 trim kits with other Posi-Temp series valves?
Gibson T2903 series trim kits are designed for use with specific Posi-Temp valve bodies. While the Posi-Temp platform shares common dimensions, trim kits are matched to valve series for proper fit and function. For example, a T2903NH bathtub spout and shower arm combination includes a pull-up diverter and is intended for T2903 series valves. Cross-series compatibility is not guaranteed. Always verify the valve model number and consult the manufacturer's literature before substituting trim components.
What connection types are used in Gibson tub and shower faucet combinations?
Gibson tub and shower faucet combinations, such as the Posi-Temp T2903 and T3003EP series, use IPS (Iron Pipe Size) connections. IPS is a standard threaded connection for plumbing fixtures. This connection type is common in residential and commercial applications and allows for straightforward installation with standard fittings. When replacing a tub spout or shower arm, confirm the connection type matches the existing rough-in to avoid adapters or rework.
