+# Service Water Heating - Rule 11-5
+
+**Schema Version:** 0.0.37  
+**Mandatory Rule:** True  
+**Rule ID:** 11-5  
+**Rule Description:** Piping losses shall not be modeled.   
+**Rule Assertion:** Options are PASS/FAIL/NOT_APPLICABLE/UNDETERMINED  
+**Appendix G Section Reference:** Table G3.1 #11, proposed column, f  
+
+**Evaluation Context:** Each SWH Distribution System  
+**Data Lookup:**    
+**Function Call:**  
+
+**Applicability Checks:**
+- Every Proposed distribution system is applicable  
+
+
+## Rule Logic:
+- Get to the `service_water_heating_distribution_systems` level
+    - Define a list that stores the pipe data: `piping_losses_modeled = []`  
+    - Loop over the `service_water_piping` object: `for service_water_piping in swh_dist_sys_p["service_water_piping"]:`
+    - Store the current piping obj: `queue = deque([service_water_piping])`
+    - Check the `are_thermal_losses_modeled` value including all the child pipes: 
+    -    `while queue:`  
+        -   `current_piping = queue.popleft()`  
+        -    `children_piping = current_piping.get("child", [])`  
+        -    `queue.extend(children_piping)`  
+        -    `piping_losses_modeled_p.append(current_piping.get("are_thermal_losses_modeled"))`  
+
+    **Rule Assertion:**  
+    - Case 1: piping losses are not modeled, PASS: `if not any(piping_losses_modeled_p): PASS`
+    - Case 2: piping losses are modeled, FAIL: `else: FAIL`
