Dip tube for Rheem PVW50 water heater - Rheem Water Heaters

All dip tubes on water heaters smaller than 75 gallons are 3/4" male pipe thread to screw into the heater. As for length, go to a plbg supply and ask for a dip tube for a 50 gallon heater, and if it is too long, cut it. I believe that Home Depot also has them right out on the floor for sale.

certain water heaters had a tube that dissolved, you take 1/2 in. copper flare one end of it, drill a1/8 in. hole in pipe 4 in. below flare ,remove cold water nipple on tank install new copper tube, cut tube to 3 inches off bottom of tank depth , reconnect cold water supply you should be good.

Your water heat is at an age that I would recommend replacing the whole unit. That one cannot be too efficient and most likely has sediment built up on the bottom of it pretty bad.

Why is it always Rheem problems?
Every water heater problem is Rheem.
And Rheem doesn't post any service manuals, like the other two big manufacturers, AO Smith-American, and Bradford White.

You have a water leak coming out of side of tank?
Water heater must be replaced. It is rusted, and could rupture.
Inspect and replace anode rod to prevent rusted tank, so water heater will last longer.

Water heater can test for 120V power on elements and thermostats at all times.
That's because thermostats turn off one leg of 240Volt circuit, and not both legs.
You mentioned thermostats and elements, implying two elements and two thermostats, so your water heater is 240Volt.
240Volt breaker might be bad on one leg.

1) Rheem power vent series:
http://www.rheem.com/product.aspx?id=C24E3F52-A6A4-4BC7-AF5B-0DF23A7A0263

2) Looking at product over-view manual: It says 'inlet connects directly to a dip tube which directs water to bottom of the tank.'
So it appears that dip tub is connected to heat trap nipple on cold water side

3) Sample manual for Rheem shows exploded parts list
http://globalimageserver.com/fetchDocument.aspx?id=a92c7d0e-8a95-48ba-8810-cd714f33d47a
The exploded view shows cold water nipple separate from dip tube, and shows dip tube gasket, and makes it unclear

4) Manual shows Rheem phone number:
1-800-432-8373

You may want to check the heating elements first. Where I live there is a lot of lime in the water that can coat the elements.

With Rheem you have to back to the installer.Most of the heater have ten year warrany.
