I Have A Valley Shower Faucet Live In Mobile Home No Hot Water Pressure In Tub/shower, All Three Sinks Have Great Pressure. So Far I Have Drained A Gallon Of Water From Hot Water Tank. Shut Off Water Main Took Out Cartridge And Seats And Springs Turned Main Back On For 5 Min Looked At Faucet Still No Hot Water Pressure Even With Nothing In It. Held Finger Over Cold Water Hole To Flush Hot. Shut Off Main Put In Brand New Springs And Seats And A Brand New Cartridge Turned Main Back On.

Still No Hot Water Pressure In Shower Don't Know What Else To Do??

Still No Hot Water Pressure In Shower Don't Know What Else To Do?? Renove the knob and chrome face plate and Look up where the hot water connects to the valve,(see image). This is a screwdriver shut off or integral stop. It's a shut off so you can service the valve. Shut the water off at the house shut off or the hot water heater and remove the stem and washer assembly from the screw driver stop. Feel around the seat for a blockage. Now turn the hot water back on to flush out the supply and screwdriver stop. Do you have a full stream now? Good luck, Tom

I do not have shut off screws looked. But I did do everything else you stated and no help
Thanks

OK! That puts the problem in the hot water supply. If I were there I would cut the hot water supply loose from the shower valve and disconnect the hot water supply from the lavatory faucet. I would then take a air compressor or air bottle and attach it to the lavatory supply and attempt to blow the obstruction out of the system. Good luck, Tom

Going to try that tomorrow cousin coming with an air compressor but we did not know how to go about using it to blow line, thanks will let you know how it works out.:)

Your biggest hassle will be adapting the compressor to the lavatory supply. If you run into a problem click on back for a little help;. Cheers, Tom

Speedball one question before I attempt this tomorrow. If the hot water pressure is perfect in the lav sink -hot water supply than how will that blow blockage all the way to the hot water supply in tub.

And any suggestions on what PSI to use?

Thanks much:)

I'm closing the entire system off, ( shut the cold water off at the water heater and close all hot water faucets.)and pressuring up the entire hot water system through the lavatory supply with the terminal outlet being the tub/shower supply that you have opened up. This will force water back through the tub valve supply. It will be a weak stream at first but when the stream becomes strong chances are you blew the blockage out. I would start a 100PSI and go up. This might kick off the T&P valve on the water heater but it will only be for a short while. Let me know how you made out. Good luck, Tom

Thanks so so much I sure will let you know if it works. Keeping my fingers crossed:D

Hi was thinking your statement

This will force water back through the tub valve supply. It will be a weak stream at first but when the stream becomes strong chances are you blew the blockage out

How will water flow in a stream than strong through hot water line when hot water is shut off at water heater where does water come from?
Thank you

Well my cousin wanted to try his way shut off main took out cartridge and seats/spings and is blowing air in the hot water 75 psi hole no improvement

Now using 100 psi blowing from hot water supply line on top of hot water heater no improvement

The water wii come from the water remaining in the pipes

Since your cousins method didn't work, (he provided no terminal outlet) now give my way a try. Good luck, Tom

With water main shut off and hot water heater on hot water burst out good with water main back on cold water burst out and hot water went down to a trickle

Do you mean by terminal outlet an open faucet?

OK just did exactly what you instructed. Not much pressure to terminal supplu but we than reversed and sent air from terminal supply (tub) to lav and great pressure does not make sense?

It means that you blew the clog into another branch. Does the tub valve have pressure or is there still a problem?

You are not going to believe this as I said I live in Mobile Home after hours of frustration hope this helps someone else with same problem, my cousin cut out the wall behind shower and about 12 inches down from hot water supply connection was a SHUT OFF VALVE and the cold water also has a SHUT OFF VALVE in between the WALL where no one could ever see or reach or touch?? Crazy or what?
This home built my Keiser.

Seem the hot water shut off valve was not fully open some vibration must have turned it (only a guess). Any way now have perfect hot water pressure but 2 big holes in my wall.

Going to repair it with a door haha

Back in the 70's I worked as a plumber in mobile home factories in my area. (not Kieser) Lots of mistakes going out the door that are picked up when the unit's set up and .ready to be occupied. Sometimes they're missed, like yours. Glad you located the trouble. Give because a pat on the back for a job well done and buy him the best steak in the house. Regards, Tom

Thanks so much just hope this helps someone else in the same situation.
Have a good one
