About this file
This document is an RFI (Request for Information) Response addressing existing steam pressure reducing valves (PRVs) observed during a site walkthrough for contract 561A4-23-101. The inquiry sought clarification on whether existing PRVs at multiple water heaters should remain, be removed, or be replaced, and requested PRV specifications and operating pressures if replacement was required.
The response clarifies that the contract drawings do not include any steam pressure reducing valves, establishing that: (1) existing PRVs are not intended to remain and should be removed if they fall within demolished steam piping; (2) no PRV replacement is required, as water heaters are designed to operate at building steam pressures of 15, 25, or 30 psig depending on the building; and (3) where an existing PRV is present but undocumented on drawings, the new water heater must be connected directly to the steam system per the contract drawings, with undocumented PRVs removed or bypassed. The response confirms these conclusions align with all mechanical, plumbing, demolition, schedule, and schematic drawings in the provided 100% Design Development (DD) set.

561A4-23-101 RFI Responses
Existing Steam Pressure Reducing Valves
During the site walkthrough, existing steam pressure reducing valves (PRVs) were observed at several water heaters. Some PRVs are still connected, while others appear to have been removed or bypassed.
The contract drawings identify the steam pressure serving the water heaters but do not clearly indicate whether the existing PRVs are to remain or be replaced, please clarify?
Are the existing PRVs to remain, be removed, or be replaced?
If replacement is required, please provide the required PRV specifications and operating pressures?
Where an existing PRV is present but not shown on the drawings, should the new water heater be connected downstream of the existing PRV or directly to the steam system shown on the drawings?
The contract drawings do not include any steam pressure reducing valves (PRVs). Therefore:
1. Existing PRVs are not intended to remain and should be removed if they fall within demolished steam piping.
2. No PRV replacement is required, and no PRV specifications or operating pressures are provided—water heaters are designed to operate at the building steam pressures shown (15, 25, or 30 psig depending on building).
3. Where an existing PRV is present but not shown, the new water heater must be connected directly to the steam system per the drawings; undocumented PRVs should be removed or bypassed.
These conclusions align fully with all mechanical, plumbing, demolition, schedule, and schematic drawings in the provided 100% DD set.
