Is it wise to add a shut off valve?

(1/2) > >>

brownnugen:
I have a Tidalfit swim spa the I recently picked up off of Facebook marketplace.  When I opened up the cabinet to take a look at the variable speed pumps, I noticed there were no (visible) shut off valves going into the pumps.  I just drained the swim spa and was wondering if it would be advisable to take time and add shut off now.

My thinking is if any kind of repair to the pump were needed (crossing my fingers I will never need to), a shut off valve just before the pumps would prevent me from having to drain 2,000 gallons of water.

Has anyone ever done something like this?

2 sides to every pump so you will need to add 2 gate valves...one before and one after

Easy Peasy, good idea.

brownnugen:
I should clarify-  in my original post, the pumps I was referring to are the variable speed pumps for the swim jets.

After doing a little more exploring, I found a Gate Valve at the circulation pump.  Would closing that valve serve the same purpose of being able to not have to dump all my water if I had to remove a pump? 

CanadianSpaTech:
There has to be a gate valve on each side of each pump. You can't close just one gate valve. If there is one at the circulation pump I'm sure if you follow the plumbing line there will be another...likely on the other side of the heater so if you had to remove the circ or the heater/spa pack you would be able to isolate that area in between the 2 gate valves. It would not isolate the main pumps unless they have their own valves again one before the pump and one after so you can work in between and remove the pump.
