9 Technical Questions on the Ultraflow Conversion kit - Ivory

Question

How do I stop heavy water leaking from my Carver Crystal 2 socket whenever a tap is turned i.e. the pump operates. I have changed the non-return valve on the hot water tank, bought a new whalemaster (suitable for Carver Crystal 2 socket) pump. Do I have to buy a new Carver Crystal 2 inlet unit ? Any ideas?
on

Answer

You may have a hairline crack in the housing of the Crystal 2 inlet in which case you will need to replace it or upgrade to the Ultraflow conversion kit.

Question

Hi, I have a Lunar caravan which is permanently in the South of France. Do I need to replace the Crystal MK2 filter housing as it leaks externally around the filter thread and if so does the conversion kit contain all that I will need to operate the pump again. How about electrical connections and filters. I need to make sure I have all that I need before I go there in June as France is not easy to find spares. Thanks in anticipation,

Answer

The Ultraflow conversion kit will replace the Crystal Mk 2 and the kit contains all parts that you will need apart from a little mastic to seal the housing to the side of the caravan. Reference no. for kit 235667.

Question

Hi there, Wonder if you could help me please. My carver crystal water pump mk 1 has been stolen from my caravan along with the front flap casing.

It's my first caravan and I a gutted. Thank you Emma

Answer

You will need an adaptor plate, our ref. 233280 together with an Ultraflow Conversion kit, our ref. 235667. You will also need to buy a pump and part 205895 will be suitable together with blue hose 232665.

Question

We have a 1987 ABI Ace Ambassador caravan which is is fitted with I believe a Carver Crystal MK 1 cold water only system. The water pump and inlet hose are permanently attached to the filter housing and stored behind a slide out/ click fit flap when not in use. Due to old age the plastic has cracked and become fragile. I notice that you sell an adapter plate (product ref. 133278) which allows the Crystal MK 2 to be fitted in lieu of the MK 1. I do not really want to replace the MK 1 filter housing etc. as all is working OK. Is there a flap available which would fit adaptor plate and allow me to continue with the existing pump/ hose system?
on

Answer

Sorry, no spares for the Crystal Mk 1 are available and the only place that you may find a 'flap' to suit is at a scrap yard. If you consider changing the inlet then the Crystal Mk 2 has been superceded by the Ultraflow and the adaptor bracket is our ref. 133280. The Ultraflow conversion kit would also be required, our ref. 135667.
Amended.


Question

what water inlet unit will fit on my 2000 elddis caravan as i cannot get new filters for the old one
on

Answer

It is likely that you have the Carver Crystal Mk 3 system for which the filters are obsolete. You can replace with the Truma Ultraflow system and the conversion kit is our part 135667 (ivory) or 135666 (white)

Question

Hi Tom. I've got a crystal compact mk2 water socket/pump fitted to my 2001 caravan and I'm having some connection problems. It'll work intermittently, then I'll have to give it a little wiggle and it'll start again. Also sometimes the pump will be running even though there are no taps on. I notice that it is obsolete, so if I need to change it what is the alternative part. Many thanks :-)

Answer

There are generally two types of water systems used in caravans. The first is the microswitch system where each tap is fitted with a microswitch. When the tap is opened the switch is turned 'on' and power is supplied to the water pump. This pump is normally a submersible pump that drops into an external water container. When you close the water tap then the switch is turned 'off' and the pump will stop. If the pump continues to run then there is a fault with the microswitch which normally means that it will need replacing. The switches in the taps are wired in parallel so that whichever tap you turn on, power will be supplied to the pump.
The second system is the pressure switch system. With this arrangement you have a pressure switch in the water system which senses the water pressure. When you open a tap the pressure in the system will drop, and this drop in pressure on a diaphragm in the pressure switch causes movement of the diaphragm. This movement has the affect of turning the switch 'on' and thus supplying power to the water pump. Conversely when you turn the tap off the pump will continue running for a few seconds which has the effect of building up pressure in the system. This increase in pressure again causes movement of the diaphragm in the pressure switch which has the affect of turning the switch 'off' and thus stopping the pump. If the pump continues to operate after the tap has been turned off then it may simply be due to the pressure switch needing adjustment or there may be a fault with the pressure switch where a component or the whole assembly may need replacing.
With pumps such as the Shurflo or Flojet the pressure switch is part of the pump itself. On some systems where the Crystal 2 water inlet is used the Whale pressure switch, our ref 105500, is installed in the cold water pipe work, normally under a seat and close to the water inlet. On the Whale Watermaster system the pressure switch forms part of the water inlet and an adjustment screw can be found on the rear of the inlet.
The Crystal 2 water inlet has now been superseded by the Ultraflow inlet and a conversion kit is available, our ref. 135667.


Question

Being told that 127838 will replace my present Carver Crystal 3 water inlet housing but the connections look different. Do connections come with the new housing or do i require new to suit?
on

Answer

Part 127838 is the Crystal 2 system and pre-dates the Crystal 3. The item that supercedes both is the Ultraflow system and the conversion kit is our part 135667 (ivory) or part 135666 (white). Either will fit into the same hole as the Crystal 3 and includes a new connection for the water pump.

Question

Hi Tom, I am replacing the Carver boiler in my Compass Reflection caravan with a 'Henry', but wish to replace the Crystal filter assembly at the same time, as the original is seized closed and I cannot change the filter cartridge. Is a replacement filter assembly available, and will I be able to use the original plug-in hose/water pump assembly? Many thanks, Chris
on

Answer

The Crystal Filter assembly is replaced by the Ultraflow and a conversion kit is available, our ref. 135667, which includes a new plug to fit to the pump hose.

Question

I have a Lunar van fitted with Truma Crystal Water system. It has failed and I want to replace it with Truma Ultraflow system. Is this something I can do myself? If so can you supply the necessary parts and at what price?
on

Answer

Yes, this is a fairly simple task. Undo the four screw holding the existing box and remove cleaning all the mastic from the caravan. Fit the new Ultraflow Conversion Kit in the same hole using some non-setting mastic to seal. Secure with four self tapping screws. Fit the new plug connection to your submersible pump.

Replacement For An Old Carver Crystal Filter Inlet

by Beargarden (31 May 2012)
5 star review(5/5)
After replacing the old carver crystal unit twice in 6 years, installed the new model ultraflow. Much better design especially the filter thread, which breaks too easily. (Can't believe it took so long to come up with a replacement design!) The screw locations for attachment are different to the old model so care is needed in offering up and drilling for the new installation.
