SK1500-3

A: 

Just talking about making sure that the outside of the piston is well greased and it moves freely when in the shower body.

A: 

Sounds like it is sticking inside, it is going to need a strip down clean lube and a service kit fitted.

A: No, just fit them the same way as they came out.

A: 

With the Sirrus 1500 or 1800 series that in almost every occasion the first thing to do is give them a strip down clean and lube and fit a service kit, this will cure 85% of any problems and it is also the cheapest thing to do.

If after servicing you find out that it needs a thermostat or piston, nothing is really lost because it almost certainly needed a service in any case.

The 1500

http://www.showerdoc.com/shower-spares/sirrus-by-gummers/GUM-PARENT-34-Sirrus-1500---Thermostatic-Shower

The seal that shuts the water off is the seal that fits into the base of part 5 in an old valve this looks like a flat washer, it is in fact a thick heavy ‘O’ ring, this can be a difficult seal to fit.

When fitting make sure that all the old seal is removed and no bits are hiding under the lip, give the seal a heat in hot water and make sure that the seal is well greased before fitting, once it is pressed in there can be bumpy bits on the face of the seal, rolling and pressing a screwdriver handle over the bumps a few times can help to smooth them out.

The seal housing is available which has the washer already pressed in if for some reason you have difficulty fitting the new seal.

A: 

The normal cause of this is the piston sticking so checkthat it is well greased

You can check the thermostat

To test the stat you need a cup of hot and a cup of coldwater and a felt tip pen

 

Dip the brass part of the stat into the cold water for10secs then mark with the felt tip the steel pin as it comes out of the brasscapsule now dip it into the hot  cup thepin should move out about 2 to 4mm dip it back in to the cold and it shouldretract.

The way to set the temperature is to turn on the shower tothe hottest position remove the centre screw water will dribble out, this isOK, insert a long thin screwdriver down through the centre of the valve in tothe temp adjusting screw, screw clock wise for hotter and anti clock wise forcooler .

 

A: 

The only think I can think of that matches your description isthe piston.

 

This comes as part of the piston and stat kit

If this is not the part you are referring to then can yousend me a photo.

A: 

 Unfortunately there  is no fitting instructions for this

 

However this is an exploded view of the valve

http://www.showerdoc.com/shower-spares/sirrus-by-gummers/GUM-PARENT-34-Sirrus-1500---Thermostatic-Shower
Once you unscrew the main body of the valve the first thing that should comeout is the thermostat capsule just watch that the new one goes back in the sameway round .....With the with the steel pin facing out ...To you and the brassbody sitting in the piston

 

When you have it stripped this far down make sure that youclean and grease the piston with silicon grease

 

The piston should just fall out or it may need a wiggle.

 

Take photos as you go.

A: Would recommend stripping down , cleaning thoroughly , fitting a seal kit and lubricating with silicon grease.

A: 

Sorry for the delay in replying

 

Yes they use the same stat. and piston

With the Sirrus 1500 or 1800 series that in almost every occasionthe first thing to do is give them a strip down clean and lube and fit aservice kit, this will cure 85% of any problems and it is also the cheapestthing to do.

If after servicing you find out that it needs a thermostator piston, nothing is really lost because it almost certainly needed a servicein any case.

 The 1500

The seal that shuts the water off is theseal that fits into the base of part 5 in an old valve this looks like a flatwasher, it is in fact a thick heavy ‘O’ ring,  this can be a difficult seal to fit.

When fitting make sure that all the old sealis removed and no bits are hiding under the lip, give the seal a heat in hotwater and make sure that the seal is well greased before fitting, once it ispressed in there can be bumpy bits on the face of the seal, rolling andpressing a screwdriver handle over the bumps a few times can help to smooththem out.

The seal housing is available which has thewasher already pressed in if for some reason you have difficulty fitting thenew seal.

The 1800

There is no real difficulty with this valvehowever it is a little more complicated than the 1500 just take photos as youstrip it down you can then refer to them when you are rebuilding.

 

 

A: 

I would give it a strip down clean lube and fit a service kit

It may need a thermostat however the normal problem is the internals sticking so it makes more sense to do them and fit the more expensive stat and piston kit only if necessary.

A: You may have to adjust the temperature control as follows,
Turn temp control to maximum remove knob insert a long thin flat bladed screwdriver engage the adjuster and turn anticlockwise to increase temperature , aloow about 15 to 20 seconds to allow stabilisation once you have reached the max temp you require refit knob in maximum position.

A: Aeraid not , Sirrus only supply this as a kit , it can be ordered online by clicking on the link below.

A: 

I think you have probably ID’d  the problem.

 

However just to do the checks......

Is the valve fitted hot to the left cold to the right?

If it is fitted correctly then I would have it off the wall and check that the inlet filters are clear and that the check valves (if fitted )are not sticking

It may also be worthwhile giving it a strip down, clean, lube and fitting a service kit.

A: 

Probably just needs a strip down clean lube and a new seal kit fitted

 

Here is the link to the kit

A: Yes this is the correct stat and piston for this valve

A: 

Yes this is the correct thermostat and piston for the TS 1700

A: 

First check that the hose is OK and hasn’t collapsed internally  then I would  check the filters and check valves in the inlet elbows are clean and clear.

A: 

If there is only one broken lug then this shouldn’t cause the pump to hunt. 

The usual things that cause a pump to hint is poor water supply, so can you check the pump and shower inlet filters and make sure that they are clear.

 

The other possible fault, is faulty flow sensors on the pump

 

 

 

A: This shower will not change temperature untouched, but it may be causing the boier to cycle hot and cold if there is not sufficient flow .
Check that the hose is not kinked or collapsed internally and the head is clear.
If they are ok then it is definitely a boiler problem

A: After adjusting with screwdriver did you leave it for about 10-15 seconds to allow it to stabilise before checking ?
If the shower is supplied from a combi boiler or an unvented hot water cylinder then it may be that col supply pressure is too high, if so a pressure reducing valve may be needed in the cold supply to the shower.

A: 

I am not sure I’ve have you exactly correct but if you mean the seal that comes with the kit, that seal should be fitted into the shower body and the shuttle rubs up and down against it
