Waltec washerless faucets

Cartridge may be bad or there is dirt or something in ceramic cartridge.

Shut your water off to the faucet and remove lever handle by untighting the set screw on the handle with a 1/8" allen wrench. Remove handle and sleeve that handle sits on to gain access to stem to remove seats and springs I have included a web site go to it and click on parts diagram to get a exspoded view of internal parts.

Hope this will be helpful to you.

If a faucet is leaking the necessary repair will be either:
1. For a ceramic or washerless faucet, replace the cartridge.
2. For a typical old fashioned faucet, open the faucet, replace the washer (and packing if it has any) and verify that the faucet seat has not eroded.
The newer washerless faucets cannot be repaired except by replacing the cartridge. Cartridges for most common faucets are available at most home improvement stores or plumbing supply houses.
It sounds a lot more difficult than it really is, just shut off the water (usually a shut off valve under the sink). After the water is off, remove the handle and any chrome protective covering. Depending on the faucet type, it may be a little difficult to remove the cartridge since they are often covered with mineral build-up or corroded into place.
Once you remove the old cartridge the new one usually goes into place easily.
NOTE!!!
For single handle faucets, make sure you put it in the right way, some of them will put the hot to the wrong side if you put them together backward.

hi, just had a quick look and the part you would have to source would be :78125 spline adapter. this is shown here...... http://www.us.kohler.com/onlinecatalog/pdf/1146603_2.pdf the taps are washerless ceramic valves and pretty good quality, are they still covered under warranty as i would imagine that part is not cheap.

There are a number of reasons your faucet may not be shutting off. If you have an old type of faucet, the problem may be due to a worn out washer, or the faucet may have a damaged seat. In which case, there is a tool that can be purchased in your neighborhood hardware store. You will have to disassemble the faucet and examine the seat to verify the damage. In older faucets, it is sometimes better to replace the faucet than make the repairs, as the repairs and the search for parts to repair the faucet may be almost impossible to find.

Or you may have a washerless faucet which actually has a different type of spring loaded washer, and will wear over a period of time as well.

The shut off valve may even be somewhat loose and require tightening. In most cases, this can be verified if the handle turns 360 degrees and never tightens completely.

I hope this helps you solve your problem

Turn water off, dismantle retainer remove and replace cartridge or remove rubber valve rubber with head of small common nail,pull out springs and get replacements at hardware store for specific application, or for a quick fix, strech springs slightlyand reinstall.

I have a Waltec vegetable drainer which fits perfectly in my sink (the sink is about 10 years old) and I am having trouble finding a replacement. Where would I find such products?

Check that we were looking at same parts diagram, but I would say RP-70 Ball assy., as well as RP-4993 Seats & springs . If it's only dripping, just seats and spring will usually get you by, but if they are sending parts, free of charge, or ball assy., isn't too expensive, I'd change it too. I have had some luck with removing ball assy, cleaning it well with fine steel wool, then removing seals, and springs, stretching spring slightly, to add more pressure to seal, clean seal, then dab on a little vaseline to seals, and re-assemble.
