Saw one today with 5 bends. Would this create too much back-pressure if the valve is activated?

Probably not, if the pipe/tube was joined correctly.
03 IRC P2803.6.1 does not call out maximum number of bends. As long as it is gravity drained. For my next trick I will need a volunteer ps some of the opinions I have posted here may or may not be factually based. AZ Cert # 39975 AZ Pest # 050898

You may want to check manufacturer installation requirements.
For example ...from AO Smith manual... The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9.14 m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve, see Figure 10. |
