Older Waltec tub shower 'growmax' needs replacing

From 1970''s - 1980's Waltec manufactured the 'gromax' used to adjust water temperature. There was a 3 knob vertical configuration. The top knob regulated shower strength, on + off. The bottom knob regulated the tub strength, on + off. The middle knob regulated the temperature, hot or cold for either the shower or tub, which ever was selected. I would like to see the plumbing configuation behind the wall and want to know what to use to replace this old system, as they are no longer made. (It's really too bad as they worked great and had a safety feature for young ones. If someone has one lying around on a shelf I would love to buy it!) I'm not sure how to spell 'gromax'? This is for my Mom's bathroom in Canada.

SOURCE: Triton T90si electric shower temperature stuck on hot.

It sounds as though the valve is not closing and opening properly. I would have a proffesional come out to have a look. I could also be the control board not working correctly or a combination of both.

What brand plumbing in shower

most taps for bathrooms have replaceable spigots and handles of various design that suit the shaft. I would be talking with a plumber as to what you have and as to why any spigot assy will not fit. Even if you have ceramic inserts they still fit the tap proper.

Grohe avensys dripping

Hi Bryan,

The leak you're seeing originates at the hot / cold water valve(s) itself. Most newer homes have valves that automatically adjust the temperature of the water to prevent scalding. Your Grohe Avensys, like many reputable makers, have warranties on their products and may make replacement parts available for free - if you are still under warranty - by call their customer support lines.

Generally, you will not be able to get free replacement parts at a hardware store, plumbing supply store, etc. You must call the manufacturer directly. Of course, you will have to pay for these parts at those retailers - if the valve is out of warranty, been replaced by the manufacturer under warranty previously, etc.

Your first step will be to identify the valve model. This information may be near the manufacturer's name - or may require locating the manufacturer's web site for visual comparison. Either way, you'll probably need to contact the customer service representatives to get help with replacement parts. They should be able to select the parts that you need to solve the problem and provide them along with printed removal & installation instructions.

I hope this helps & good luck!

We had a new battery put in our 1999 lincoln navigatior and the rear air suspence went down and we can not get it to to fill back up

Replace the entire Air Suspension with
conventional shock/struts such as Strutmasters
or other brands

You do not even diagnose a Navigators Air
Suspension after the vehicle is 5 years old
Dealers can't figure it out

Next time you get the Ford version.
Still issues but nowhere near anything
that is installed on a Navigator

A Navigator is like an Oldsmobile from
the 1970's & 1980's A test bed of poor choices,
bad engineering & ideas

When I turn on the tub faucet, water comes out of the spout and shower head. It's a t215.710 model

Does it have a diverter on the spout? If so, replace the spout with the same type. If it is a new installation, did you make up the valve or was it complete and designed for tub & shower? If it's an old valve and it has a separate diverter stem, there is a spacer behind the valve between the valve housing. Replace it.
