My TerraTop® or my SubTerraneanT I is leaking where the dome and base connect, what can I do?

TerraFlo® products are hand-tightened at G.E.T.'s plant. It is possible that the dome is not turned tightly enough on the base. Try to hand tighten the dome to the base as hard as you can and then turn the water back on.

If it is still leaking, hold the base and dome over a sink or basin, unscrew the dome from the base and check to be sure that there is a black 0-ring in the groove of the dome. If it is not there, please call G.E.T. at 610.821.4901. The 0-ring is required for a watertight seal.

If the 0-ring is present, check to make sure it was seated flatly in the groove. There should be no kinks or slits in the 0-ring. It must be smooth and round to create the watertight seal.

If the 0-ring was not kinked or slit, lubrication is our next consideration. The 0-ring is lubricated in G.E.T.'s plant with a non-petroleum-based jelly called Vegelatum. This lubricant prevents the 0-ring from drying out and changing shape, and provides a watertight seal between the dome and base. It is possible that the amount of lubricant applied was not sufficient to make a watertight seal. Re-lubricate the 0-ring with Vegelatum, Vaseline, margarine, or cooking oil.

If none of the steps above have stopped the leak at the dome/base connection, please call G.E.T. at 610.821.4901.

 

I can't get my TerraTopT CBLX Diverter Valve to attach properly to my faucet, what can I do?

After you have unscrewed the screen portion from your faucet, are your threads on the outside or are they in the inside of your faucet? If the threads are on the outside of your faucet your diverter valve should screw or attach directly onto your faucet.

If the threads are on the outside and the diverter valve does not attach properly, you need a specially ordered female metal diverter valve adapter. Please contact G.E.T. at 1.800.800.8377 to place an order.

If the threads are on the inside of the faucet you will have to use one of the two plastic inserts supplied in the hardware package. One insert is slightly larger, measuring 15/16". The smaller one measures 13/16". Determine which insert screws or attaches easily to your faucet. After you have found which insert will work for you, screw the plastic insert into the top of the diverter valve. Then screw the diverter valve/plastic insert attachment onto your faucet.

Once the diverter valve is attached, check for any leaks at the diverter/diverter plastic insert connection by turning the cold water on. If there are leaks, please read the section below.

 

I have my Diverter Valve attached to my faucet but it still leaks, what can I do?

Unscrew the diverter valve or the diverter valve/plastic insert attachment from the faucet. Take the white rubber washer (supplied in the hardware kit) and place it into the top of the metal diverter valve or on top of the plastic insert then re-attach it by screwing it back onto the faucet.

If the TerraFlo® continues to leak at the diverter/diverter plastic insert connection carefully tighten it slowly and gently with a wrench. Be careful not to strip the plastic threads. If the leak still persists please call G.E.T. at 610.821.4901.

 

I can't get my TerraTopT or my SubterraneanT I open to replace my filter cartridge, what can I do?

TerraFlo® products are hand tightened at G.E.T.'s plant. Sometimes the dome is difficult to unscrew from the base because of the water pressure that has built up within the unit.

If you own a TerraTop®, unscrew the diverter valve from your faucet to relieve some of the line pressure. This will probably allow you to open up the system

If you still cannot open the system, try the following:

With the diverter valve unscrewed, tap the dome gently on a soft surface as you would to open a lid on a pickle jar to alleviate any pressure build-up.

If you still cannot open the system you may need to request assistance from another person with more strength.

If you own a SubTerranean™, shut the cold water valve off first. This valve is located under your sink on the pipe that supplies the cold water to your sink. Next, depress the fountainhead lever to drain the water under pressure in the housing(s). Next, open the non-filtered cold water faucet valve mounted on top of your sink to drain any water in the line. This will relieve water pressure between the cold water shut off valve that you have closed and the and the faucet valve mounted on top of your sink. Then follow the instructions for the TerraTop® to unscrew the dome the from base.

Note G.E.T. will not accept any returns because of a customer's inability to unscrew the dome from the base to replace a filter cartridge.

 

I have just installed my SubTerraneanT I and I have very low water flow coming out of the fountainhead, what can I do?

The cause of low water flow depends on the type of installation you have. First, be sure you installed the saddle valve to copper, galvanized, or some other form of metal pipe. The saddle valve does not properly puncture flexible tubing or pipe.

If you have flexible tubing or pipe, you must install the system directly in line by cutting into the pipe. A "T-fitting" is required, and we recommend you consult with a plumber if you are unfamiliar with this type of installation.

If you installed the saddle valve to copper, galvanized or metal pipe, did you turn the winged piercing valve nut clockwise to pierce the cold water pipe?

If you missed that step, turn the winged piercing valve nut slowly and gently until you feel the pipe puncture. Then turn the winged nut in the opposite direction to open the saddle valve. You must make sure to "back out" the saddle valve's piercing pin to allow the water to flow through the hole that it made.

If you still have low water flow from the fountainhead, check to be sure that you used one of the two tube inserts, supplied in the hardware package, at the saddle valve and the fountainhead installations. The tube insert looks like a T and is either brass or white plastic. The tube insert prevents the plastic tubing from collapsing or crushing when tightening the compression nut with a wrench, which would cause low water flow.

If you still experience reduced water flow coming from the fountainhead, check to be sure that you used both plastic delrin sleeves, if you used the plastic tubing provided by TerraFlo®. If you used the brass delrin sleeves (which only should be used with copper tubing) the brass delrin sleeve may have slit the plastic tubing and created a subtle leak which would reduce the water flow.

If the water flow coming out of the fountainhead continues to be decreased after the above steps have been followed please call G.E.T. at 610.821.4901.
