I have been using tankless heater for over a year with my Mytee Escape and it gets about 120 degrees...the pump can take up to 140...I have not had any problems with it to date, I have pics and web link somewhere on TMF of it.
I have only had to deal with the pump once on the 2 vac Escape and it had frozen and cracked the seals, had to replace that one
When I first got my 4 vac ETM I had to prime it and it still wouldn't work...took me a few to realize the chemical jug was empty and needed water, also the prime tube...
On your pressure not working I would make sure you have water or rinse in the chemical injection jug
Prime it and use the vacs on the primer hose.
I would make sure your vac sensors are not stuck on the pump out problem.
On my first 2 vac Escape it came with a 70 GPM pump out, It would not activate untill the water tripped the sensors
Same on my 4 vac Escape, it has 90 GPM and will not run until the sensors are tripped by the water
There are not very many wells where I work, I do have a well at my house,
I just feel better not having to hook up to a water source, one less thing I have to do.
I have a brother that lives in the city where I service and I use his water to fill my fresh tank.
I splipped into a depression after my wife had medical problems and I lost my Grandmother who I have took care of in my home for the last 3 years and lost my Uncle the next month.
Never gave much thought to depression until it hit me like a ton of bricks, just work and keep my mind busy...
I run the Mytee Escape 4 vac ETM, I have onboard water and hose reels,
I run generator about 50% and dryer plug about 50%
I don't take but 2 jobs per day and more than likely one will be an apartment.
I can see anybody taking on 5-6 jobs per day with my setup with no problems, as I have...
