Question about Eljer Aqua-Saver 12" Two-Piece Pressure-Assist Toilet - 091

1 Answer

Eljer Flushmate Floor Mount Floor Discharge 1.6gpf rim impaction

1. the mineral impaction must be extreme inside the rim conduits, both sides.
2. i removed the tank to access the bowl's inlet plenum and attempted to lance the rim mineral impaction on both sides (symmetrical ducts and outlet ports).
3. the rim delivery conduits are rather small and the coat hanger tip got only about 8 inches maximum penetration, i think because of the meandering passageway designed. i rotated the wire while plunging and got deeper penetration but eventually hit extremely stubborn stops.
4. i need a motorized rotational flex snake of compatible diameter to clear the mineral deposits, else the eljer bowl is history.
5. what say you experts on this ? is the eljer worth unclogging ? it's in tip top condition. a surgical camera probe snake would definitely clarify the reality i'm up against.
thanks in advance,

    1. i have already failed approaching this rim impaction problem from the downstream orifices using a guitar string (.054") and also using a syringe to inject mineral solvent.
    2. i'm the second owner just moved in. 1st owner upgraded gravity flush to eljer flushmate.
    3. during pressurized flushmate discharge, there is slight weepage from the farthest orifice on one side only.
    4. the porcelain ducts inlaid for the rim by eljer may in fact be poorly designed and/or poorly fabricated during factory mass production. inspection of the bowl's visible inlet plenum shows interior forming defects, as opposed to the perfection exterior that is never hidden. the design of the diameters used for rim orifices and delivery ducts is the invitation for impaction. while true jetting velocities will be greater with smaller diameters, the tendency for mineral nucleation increases as diameter decreases because of the enhanced surface tension between the water and the porcelain in a skinnier duct.
    5. i have requested eljer provide the cross section drawing of these delivery ducts and lateral orifices because it appears these passages restrict "micro-snaking" owing to tortuous delivery curves.
    6. lastly, i have not cleaned the bowl because it is sparkling clean, not even a trace of waterline ring, same with the bath tub. this does indicate to me that minerals are scant in the home water. confusingly, the rim jets are clogged and i have yet observed any loosened minerals ejected while i lanced the ducts. very strange.

Try putting KLR or even vinegar down the tubes. also using a stiff brush and klr or vinegar, scrub the jets from inside the bowl to help remove and soften it up. your coat hanger may only be compounding the problem by packing it in harder and tighter. when you get it running again, and it is a good one, make sure and put a bowl cleaner that also softens the water. can't say brand names..... but there are several good ones.

Need to mo we an electrical power point in a brick wall in my apartment

More information is needed.
Brick wall is inside apartment... what is on other side of wall?
Open existing electrical box. Drill through back of box and drill through wall until you come out on other side of wall. Install new box #1 on wall where drill comes out. Run conduit over to another new box#2. Drill through wall again until you come out on inside brick wall where you want to relocate original box. Install new surface-mount box#3 on brick wall. Then run wiring from original box. Original box cannot be bricked over or covered with building materials since it is a junction box where wires connect.
Other option is to install extension ring on top of existing electric box. Run conduit across face of brick wall. Install new box#1 where you need outlet.
Other option is to chisel away the brick and mortar from existing electric box down to floor level (or over to door frame). This will allow recessed conduit that can be concealed with matching mortar. Then run conduit across to new location. Cover conduit along floor with baseboard, or chisel out brick along floorline to accommodate conduit, then mortar over conduit. Or simply paint conduit to match brick. You must use conduit since wires cannot be run openly.

How can I remove the Flushmate 503 to access the mounting screws at the bottom of the tank?

You will need to remove the china holding tank from the toilet bowl by removing the nuts on the underside of the china tank.

After you have the tank off the bowl, remove the two plastic lock-nuts used to mount the Flushmate into the china tank and slide the Flushmate out of the china tank.

After you install the new tank-to-bowl bolts & washers, reverse the process to reinstall the Flushmate unit and remount the china tank.

We have sloan flushmate. Can`t remove the tank to fix leak.

Not sure exactly what you mean. Are you saying you can't get the tank-to-bowl nuts off due to corrosion or that you can't loosen the two plastic locknuts that hold the Flushmate in the porcelain tank?

If the tank-to-bowl nuts are corroded and you can't turn them, you may have to use a hacksaw or reciprocating saw to cut them off and replace them with a new set when you remount the porcelain tanks.

Unless they were cross-threaded at installation, the Flushmate locknuts are pretty easy to remove.

If the Flushmate tank is leaking it will need to be replaced as they can't be patched. If a component is leaking, replacing it is viable.

The Sloan Flushmate is spraying water out of the bottom valve; instead of down, the water is spraying up and all over the tank. How can I fix this?

Without more specific detail about the origin of the spray (lower supply, discharge extension, drain valve, etc) it's hard to say what the problem is or exactly how to fix it. I suggest you call Flushmate Tech Support at 800-533-3460 (M-F, 8 - 4:30 ET). For best results, call right from the toilet.

They'll need to know the serial number, model number, fixture manufacturer, etc. to get you taken care of.

Best of luck!

I have 5 kohler pressure assist toilets with flushmate 503 series tanks in my home. Several of my bowls have minimal to no bowl rinse. My water pressure is more than adequate. I recently changed a...

There are two holes in the top of the bowl where the tank attaches. As you indicate, one hole delivers water to the jet at the inlet to trap passageway, and another smaller hole to direct water to the rim.

I have seen in some cases the gasket that seals the tank to the bowl block the smaller rim-fed hole. All you need to do is knotch the gasket where the hole is located and re-install the gasket so the knotch is located over the hole. If you have any other questions please call the 800 phone number on top of the Flushmate.

Hi and welcome to FixYa, I am Kelly.

I am sure you have the 150-403 PF/2 flushing system.
Take a look at the link below for your repair options. If you have the newer style your in luck but if you have the older style your faced with a complete flushing system change out. the first tank in the picture is the old system.

If you have the newer flush tank system you can order individual repair parts using the above link.

The tank kits that replace the one you have are not cheap but you can see the flushmate one here:
Part number is: M101526-F3EK If you net search the PN to the left.. Price $106 - $125.00 Ea.
(Be aware of shipping charges... net search the PN. Some have lower prices and free shipping.)

They come with a 10 year warranty.

Thanks for choosing FixYa,

The Flushmate system won't cause or contribute to water draining or leaking from the bowl.

Negative back-pressure in your drain/waste/vent piping could be siphoning the water out or you may have a crack in the bottom of the bowl or trapway that's allowing the water to leak out.

If the floor under the toilet (actually underneath it) or around the edge where it's caulked to the floor is wet, your bowl may be cracked. If not, your plumbing system may be siphoning the water.

Either way, you can exclude the Flushmate from the equation and focus on the porcelain fixture and your drain/waste/vent system.

Hope this helps.

The tub should just sit on the floor, and caulked around to seal out any water. If it as a fiberglass tub, you might want to put some grout under the bottom to help support it.

My sloan flushmate toil I think is backiing up. When I take the lid off and flush the toilet water shoots out the front side of the flushmate. What could the problem be or is it broken.

You may have a leak in the discharge extension, lower supply, or drain valve. I suggest you call Flushmate's tech support line (on the Flushmate label) and see if they can help you out.

Good luck
