I just put in a Jabsco head and everything works fine except there is alot of pressure as you pump the handle to get water in the bowl. When you push down. Is it possible that the water intake valve is not completely open? It is one of those old gate valves.

Anything is possible...
But I don't think you'd feel backpressure while pumping if restricted intake water flow is the problem. Do you feel the same backpressure in both the wet mode and the dry mode? If so, I suspect your problem is a blocked tank vent that's pressurized the tank, creating backpressure. The cure: clear the tank vent. Or, the toilet may have a defective wet/dry valve...a common problem in Jabsco toilets. The "valve" is actually just a little "gate" that the lever swings to block or unblock the flow of flush water...it hangs--usually in the dry mode, creating backpressure that many owners mistake for a clog downstream of the toilet. Or you could have a clog in the head discharge line...but I doubt it. Check your tank vent first...90% of vent blockage occur in the thru-hull and in the connection on the tank. Once you've eliminated all the possibilities except a defective toilet pump, I wouldn't try to fix it...I'd take it back and exchange it for another one (maybe a better quality toilet this time?).
