Caravan water pump leaking

[RonA]

Hi All,
Just had a trip away at the weekend in my van.
The Flojet R3426-500 water pump fitted to it has started to click very fast & decided to take it apart to find out why. Think I’ve found the problem as the pressure switch fitted on the bottom has water in it. A replacement switch is available & I will order a new one.
However while inspecting the pump I noticed the split body of the pump (see pics) has a small leak (possibly the reason the switch has water in it). Tried a few flow jet spares companies but don’t seem to do the seal (off white in pic)

between the two halves of the pump body.
Anybody know where I might get one or failing that a suitable sealant, bearing in mind it’s potable water.

I would throw it away and replace with a sureflow

Thanks Barking Mat, I’ll post a photo tomorrow. From the enquires I’ve made spares suppliers don’t seem to interested in the white bodied models

IMO all caravan stuff is designed to fail and be bloody expensive to replace

Following Snoopers suggestion I purchased some sealant & have now eliminated the leak on the body of the pump. Just the replacement pressure switch to procure now.
Attached is a photo of the complete pump as requested by Barking Mat

Sorry run of my feet today.

I'm sure I've got what you need.

Same motor different head.

 

[Barking Mat]

Bet it's all generic.

 

[Barking Mat]

Anything like these ones?

As you said, motor & pressure switch look identical (providing they have same rating) but the head totally different.

What do you need? Just the pressure sensor? I can pull a couple off and post if you like?

Hi BM,
After fixing the leaking body, I’m only in need of a new pressure switch. Do the pressure switches you have adjust, I only need 20 psig in the water system?

Yep, there's a little cross head screw in the top which adjusts the pressure setting, after you remove that little square cover.
