3 port valve isolation valves

[Fallout]

Would it be worth putting isolation valves either side of a 3 port valve to aid swapping if needs be. Theres an isolation on the incoming supply due to the pump isolation.

Nothing to stop you, but use full bore valves not cheap shoity ones, the valve on the pump if it is ballofix dont touch it or it will leak

Thanks, another question I have. There is a gate valve as a bypass between the 3port valve. Is this really need as there is no pump over run. The gate valve looks buggerd so was looking at changing too a auto bypass. Or renewing the gate valve

dont forget to put isolation valves before the isolation valves in case you ever have to change them
