Thermal wave ii vortec no pressure!

[Austin Willoughby]

Hey guys just bought a used thermal wave ii and its missing the 180 degree thermal valve right under the water box. Long story short I decided to run the machine with out it and test water pump. I turned the heat off so I wouldnt damage the pump. When engaging the water pump I get no pressure reading. I installed a new gauge bc the previous one got damaged in shipping. Machine cuts off after 5 seconds do to no pump pressure. I have determined the clutch works properly bc it does ingagae and spin the pump. Maybe I have it plumbed wrong? Could it be the pressure regulator is bad? I even tried direct feeding the pump with a water hose with pressued turned down really low. The part I'm missing is part number 15 and I dont want to pay 450 for a new one. Can I bypass it?

I would give Jondon a call. That’s got to be a pricing error. Should only be about $50.

That's what I thought it's at most a hundred dollar part but I called interlink supply and theres is 475.... wtf lol. It cost maybe 5 bucks to manufacture the dang thing....

Could you use this instead?

I have the exact same machine...first thing I would do is to pull the check valves in the cat pump and make sure they are not stuck open or have a broken spring...

also if someone ran it with out the thermvalve and over heated the cat pump it prbably melted the seals on the inside.....look under the pump and see if it looks like melted plastic....

Thanks jim I'm gonna go pull the cat now and inspect the internals. I'll give you a call if I run into anything interesting

Before I pulled the whole pump I decided to pull just one of the valves and it looks in great shape? @Jim Martin @Justin Legend Brands

 

[Jim Martin]

That check valve almost looks brand new but there should be a total of 6... Take a mirror and lay it underneath the head of the pump where that little plastic cup is and see if there looks like melted plastic

 

[Austin Willoughby]

I couldn't get the last one out it started to strip but looks like a couple tips on the valves are bad?

 

[Jim Martin]

if you push down in the center of the check valve and it opens and closes then it is fine...right now I am still leaning towards your water got to hot for the seals....more so because you did not have a therm valve to help regulate the heat in the water box and who knows how long someone ran it with out one.....or...if you look on top of the head of the pump...there are 3 oil ports that someone may have never oiled and it got to hot and melted it.........

Pull everything apart no melted seal that I could see.... I'm thinking I have a clog at this point

It needs to be a 3 port one from what I can tell but it may be possible to retrofit this maybe

I just replaced my thermvalve on my Thermalwave vortex 2 with that exact same one ...

 

[Jim Martin]

this is what happens when the 3 oil ports on top of the pump head do not get oil every month......

 

[Jim Martin]

and this is what happened when the thermvalve stuck closed and did not cool the water box......

 

[Jim Martin]

I just got my machine back on the road about a week ago after having to replace both the pump...and the thermvalve.......the inside of the head melted because of way to much heat....I lost all pressure I had nothing...did you pull the head off the pump......????

 

[Mikey P]

I performed my annual waste tank rinse a while back..

ok I have a thermalwave 11 vortec looks like the same one you have Jim. Been running it for three years or more accurately tech running it for last year and it’s been pretty neglected tbh. I have never seen, heard of or oiled those three holes .
is that in the service manual?

it is on the one that comes with the pump.....and there is a sticker on top of the pump that tells you to put a few drops in every month.....

Ajr might be right jim if he has the same pump as me it doest have oil holes. My pump is the 5cp3120 and it just has an oil fill hole that's it

You should tear it down and swap in a 59 blower.

the 340RS has been on mine since the day it was made....the 3000 at the end is for high temp seals.....

Yep I noticed that the manual calls for the 340 but for whatever reason mine has the 5cp3120

, which if I remember correctly cannot handle the high heat very well... mine can because it's designed with high heat seals... ... I was misinformation one time and was told that the one you have was all they were making for that machine.... It lasted me less than a year.....
