Not all jets working on Hydrosystem Whirlpool Tub

first of all you need to be draining the tub completely and removing any bath mats or items from inside. Fill the tub with hot water, ensuring that the jets are covered. You can use white vinegar, 2-3 cups of white vinegar directly to the water in the tub. Turn on the whirlpool system and run it for 15-20 minutes. While the jets are running, use a soft-bristled brush to scrub the jet openings and the interior walls of the tub. Drain the Tub: Refill the tub with clean water and run the jets again for another 10-15 minutes to rinse out any remaining cleaning solution. This should help. This is what I did with mine

try a plumbers shop as it is a whirlpool tub
you state that it is a whirlpool tub then you say don't know what brand of tub it is
whirlpool is a brand name
any way the plumbers display of bathroom units and tubs will help you as the jets used are generic and not specific for the tub

The problem you are experiencing is common to many jetted bathtubs.It is a result of dried bathing water in the tub. There are a couple of solutions to resolve this ongoing problem.

1. Use your tub more frequently as the water will not have time to fester in the pipes.
2. Use a cleaning solution made for cleaning the pipes on jetted bathtubs once every three months.

On mine it's a big button vacuum switch inside the tub - I remember there was an option for a touch switch integrated in the Sunset logo.

no such items exist. use it like a jetted bathtub or pull it out and put in a soaker tub.

Sorry, the tub will have to pulled out to find out what is leaking so it can be fixed. There is just no other way UNLESS you can open up the wall on the blind side of the tube. (but its probably and exterior wall...if the house is vinyl sided, it can be done. If brick, you'll have to pull the tub). If you just wanted to convert to a tub only, maybe Bathfitters has an insert solution...

Is it a jetted tub, or a air bath tub with holes or jets in the floor? If it has holes or jets in the floor, the control box is bad and needs replaced. If it is a jetted tub, there may be a water level sensor, if so the sensor may be bad causing the tub to turn on.

Sounds as if you may need a new switch to turn the tub on/off. You can find one on our site www.uspartscenter.com

The suction IS the water intake. it takes the water from the tub into the pump and the water comes back out through the jets.

Depending on how mechanically inclined you are, take apart the tub and clean everything out. No easy task, I know, but who want old dog hair floating around? That will be your best bet.
